6 American Meter Series and 000 Worker/Monitor Regulators Worker/Monitor sets are commonly used to provide overpressure protection. A worker/monitor installation consists of a monitor with an external static connection and a worker with an internal static connection. The regulator selected to be the monitor is set at " to 5" w.c. above the worker. The external static connection is connected at a point free of turbulence and preferably a minimum of five pipe diameters downstream. Improved Features and 000 Series Monitor Conversion American Meter offers four industrial monitor regulators the 80M, 00M, 88M and 08M. Design improvements now enable all models to be configured as Monitor Regulators. This change was effective with all and 000 Series Regulators manufactured after January 994. The advantage is that two models of the same regulator need not be stocked. All models are pre-machined to accept a monitor conversion kit. Refer to IMP 8740 for kit numbers and installation instructions. When a regulator with an OPSO is converted to a monitor, a sense line must extend downstream of the worker, as shown in the diagram to the right. CONTROLLING MONITOR /" Typical Upstream Monitor Installation

7 The American Meter Industrial Regulator Monitor Conversion The body and valve head are premachined to allow easy conversion to a monitor model. See page for more information. Rugged Construction Valve heads are ductile iron which prevents thread damage. Available as -/" and " screwed, and " flanged connections. ANSI, BSP and DIN connections available. Springs The Series spring ranges from.5" w.c. to 5 psi outlet pressure. 000 Series spring ranges from / psi to 5 psi outlet pressure. See page. Interchangeable Available in sizes from /4" through -/4" for a wide range of flow rates. One orifice is offered for both standard and OPSO models to minimize spare-parts inventory. OPSO Overpressure Shutoff for positive protection of public buildings such as schools, churches, etc. See page 5. Maintenance Three setscrews hold diaphragm case to the valve head, providing the easiest orifice and seat disc inspection in the industry. Pressure Taps The and 000 Regulators have inlet and outlet pressure taps. Relief Vent A " vent for Full Relief overpressure protection in three models, such as the 8B. Partial Relief has " vent and 000 Series has /4". See page 7 for relief performances. Durability Cast-aluminum top and bottom diaphragm case for long service life. UPSO Snap-acting lever for underpressure shutoff protection when line pressure drops drastically.

8 American Meter Regulators Other Features 8 Partial Relief Series low-pressure models have a maximum inlet pressure of 50 psi and offer outlet pressures ranging from.5" w.c. to 5 psi. 000 Series high pressure models allow a maximum inlet pressure of 50 psi and outlet pressures ranging from.5 psi to 5 psi. The Series can be ordered as Full Relief, Partial Relief or No Relief Regulator as shown in the table. 000 Series Regulators are non-relieving.

10 C and C-HC Series Service Regulators Technical Bulletin

11 C and C-HC Series Service Regulators 0 Elster American Meter The C Series pressure regulators are designed to control natural gas, air, nitrogen, carbon dioxide, propane vapor, and other non-corrosive gases in residential, light commercial, and small industrial applications. General Information Outlet pressures between.5" W.C. and PSIG are available. Operating temperature range is -0 F to 50 F (-0 C to 65 C). Maximum flow rate is SCFH (70.8 m /h). All models conform to ANSI Code B , and CGA Service-Type Regulator Specification CAN/CGA-6.8-M95. Features Variety of interchangeable orifices and spring ranges 90 Degree (Right Angle), 80 Degree (Straight-Flow), or Offset Valve Body (See photo below) Wide range of valve body connection sizes Options Vent Elbow The regulator vent opening should face downward (6 o'clock) to minimize the chance of blockage from ice and snow. If not possible, a /4" NPT plastic, 90 vent elbow (part number 7804P05) and separate protective screen (part number 70400P07) may be screwed into the vent to provide the necessary protection. Elevation Compensation The E.C. orifice is recommended for installations where the inlet pressure may vary over a wide range. The E.C. orifice is available in two sizes: /8" x /6" and /6". The capacities of these orifices are the same as the standard orifice of the same size. Full Capacity Relief Valve Full capacity internal relief valve standard on all models. (See Performance Graphs on page 9) Splashguards UV stabilized, weather-resistant, resin device that protects the vent screen from Applications Model Number 8C 8C-HC 84C 84C-HC 85C w/ USSA 85C-HC w/ USSA splashes while providing a large external vent opening to keep regulators working properly. Safety Shutoff Devices Overpressure Shutoff (OPSO) Operates independently. The OPSO will shut off the gas supply in the event of a serious downstream pressure build-up. These are available in two pressure ranges on the Models 84C and 84C-HC. Spring Range Part Number 4" W.C. to 5" W.C. 740P005 PSIG to / PSIG 740P004 When the outlet pressure exceeds the OPSO set point, the pressure under the OPSO diaphragm (A) compresses the pressure spring (B) forcing the diaphragm stem (E) upwards and releasing plunger (D). This permits the shut-off spring (F) to force the shut-off disc (G) against the back side of the special double-ended orifice.

16 C and C-HC Series Service Regulators 08 Elster American Meter C and C-HC Series Service Regulators - Other Technical Data Full-Open Regulator Relief Capacity For sizing downstream relief valves, use the following formulas to determine the regulator full-open capacity: Critical flow rates Q = 0.5 C x P G Sub-critical flows P Q = C x h G Critical flow occurs when the absolute outlet pressure is less than about / of the absolute inlet pressure. Q C P P h G Maximum capacity of regulator constant (see table below) absolute pressure (PSIA) Outlet absolute pressure (PSIA) Differential pressure Specific gravity of gas Constants C /8" 5 /8" x /6" 5 /6" 57 /4" 98 5/6" 49 /8" 08 /" 5 9/6" 4 Maximum Recommended Pressure Size Pressure (PSIG) 9/6" 0 /" 50 /8" 70 5/6" 5 /4" 5 /6" 5 /8" x /6" 5 /8" 5 This is the maximum inlet the regulator should operate at to insure complete lockup at no-flow conditions. Other Gas Capacities To determine the capacity of these regulators for gases other than natural gas, multiply the values within the capacity tables by a Specific Gravity Conversion Factor (F g). The table below lists this factor for some of the more common gases. Gas Type Specific Gravity Conversion Factor (F g ) Air Butane Carbon Dioxide Nitrogen Propane To calculate the Conversion Factor for other gases: (F g) = Specific gravity of gas on which the capacity table is based Specific gravity of gas being used Example: If using propane and only having tables based on natural gas, the Specific Gravity Conversion Factor is : (F g) = (F g) = (F g) = 0.66 Specific gravity of natural gas (0.6) Specific gravity of propane (.5) Regulator Pressure Rating 5 PSIG (8.6 bar) = Maximum recommended inlet pressure for normal service. Maximum recommended pressure may vary with orifice size. 75 PSIG ( bar) = Maximum inlet pressure for abnormal or emergency service, without causing damage to regulator case. PSIG (8 mbar) = Maximum outlet pressure for normal service. 0 PSIG (689 mbar) = Maximum outlet pressure which can be contained by pressure carrying components (no flange leakage to atmosphere except for normal relief action). If regulator is subjected to these conditions, it should be removed from service. 50 PSIG (.5 bar) = Maximum outlet pressure for abnormal service without damage to internal components. If regulator is subjected to these conditions, it should be removed from service.

21 C and C-HC Series Service Regulators 0 Elster American Meter The C Series pressure regulators are designed to control natural gas, air, nitrogen, carbon dioxide, propane vapor, and other non-corrosive gases in residential, light commercial, and small industrial applications. General Information Outlet pressures between.5" W.C. and PSIG are available. Operating temperature range is -0 F to 50 F (-0 C to 65 C). Maximum flow rate is SCFH (70.8 m /h). All models conform to ANSI Code B , and CGA Service-Type Regulator Specification CAN/CGA-6.8-M95. Features Variety of interchangeable orifices and spring ranges 90 Degree (Right Angle), 80 Degree (Straight-Flow), or Offset Valve Body (See photo below) Wide range of valve body connection sizes Options Vent Elbow The regulator vent opening should face downward (6 o'clock) to minimize the chance of blockage from ice and snow. If not possible, a /4" NPT plastic, 90 vent elbow (part number 7804P05) and separate protective screen (part number 70400P07) may be screwed into the vent to provide the necessary protection. Elevation Compensation The E.C. orifice is recommended for installations where the inlet pressure may vary over a wide range. The E.C. orifice is available in two sizes: /8" x /6" and /6". The capacities of these orifices are the same as the standard orifice of the same size. Full Capacity Relief Valve Full capacity internal relief valve standard on all models.

Safety Shutoff Devices Overpressure Shutoff (OPSO) Operates independently. The OPSO will shut off the gas supply in the event of a serious downstream pressure build-up. These are available in two pressure ranges on the Models 84C and 84C-HC. Spring Range Part Number 4" W.C. to 5" W.C. 740P005 PSIG to / PSIG 740P004 When the outlet pressure exceeds the OPSO set point, the pressure under the OPSO diaphragm (A) compresses the pressure spring (B) forcing the diaphragm stem (E) upwards and releasing plunger (D). This permits the shut-off spring (F) to force the shut-off disc (G) against the back side of the special double-ended orifice.

26 C and C-HC Series Service Regulators Technical Bulletin

27 C and C-HC Series Service Regulators 0 Elster American Meter The C Series pressure regulators are designed to control natural gas, air, nitrogen, carbon dioxide, propane vapor, and other non-corrosive gases in residential, light commercial, and small industrial applications. General Information Outlet pressures between.5" W.C. and PSIG are available. Operating temperature range is -0 F to 50 F (-0 C to 65 C). Maximum flow rate is SCFH (70.8 m /h). All models conform to ANSI Code B , and CGA Service-Type Regulator Specification CAN/CGA-6.8-M95. Features Variety of interchangeable orifices and spring ranges 90 Degree (Right Angle), 80 Degree (Straight-Flow), or Offset Valve Body (See photo below) Wide range of valve body connection sizes Options Vent Elbow The regulator vent opening should face downward (6 o'clock) to minimize the chance of blockage from ice and snow. If not possible, a /4" NPT plastic, 90 vent elbow (part number 7804P05) and separate protective screen (part number 70400P07) may be screwed into the vent to provide the necessary protection. Elevation Compensation The E.C. orifice is recommended for installations where the inlet pressure may vary over a wide range. The E.C. orifice is available in two sizes: /8" x /6" and /6". The capacities of these orifices are the same as the standard orifice of the same size. Full Capacity Relief Valve Full capacity internal relief valve standard on all models. (See Performance Graphs on page 9) Splashguards UV stabilized, weather-resistant, resin device that protects the vent screen from Applications Model Number 8C 8C-HC 84C 84C-HC 85C w/ USSA 85C-HC w/ USSA splashes while providing a large external vent opening to keep regulators working properly. Safety Shutoff Devices Overpressure Shutoff (OPSO) Operates independently. The OPSO will shut off the gas supply in the event of a serious downstream pressure build-up. These are available in two pressure ranges on the Models 84C and 84C-HC. Spring Range Part Number 4" W.C. to 5" W.C. 740P005 PSIG to / PSIG 740P004 When the outlet pressure exceeds the OPSO set point, the pressure under the OPSO diaphragm (A) compresses the pressure spring (B) forcing the diaphragm stem (E) upwards and releasing plunger (D). This permits the shut-off spring (F) to force the shut-off disc (G) against the back side of the special double-ended orifice.

Standardized Flanges: Sizes 8C through M have a 6-/4 (7mm) flange-to-flange dimension and ANSI 50 flanges for standardization in the meter set design. As loads change, meter sizes are easily interchanged, saving the cost of re-piping. Accurate Low Flow Performance: Low start/stop rates extend the rangeability (gas measured) over a wider range of flow conditions. Low Pressure Differentials: Reducing the maximum operating speed provides lower pressure differentials for low pressure applications, as well as extending the meter s life-expectancy. SERIES ACCESSORY UNITS Oil-free Design: Series accessories feature high quality and long-term reliability with an oil-free permanently lubricated design. Oil is not required for the Polymer bushings and pre-lubricated, shielded ball bearings. Permanent lubrication equates to easier installation and less maintenance. Durable, Weather Resistant Cover: Optical Quality Lexan covers on Series accessories offer exceptional Ultraviolet protection while the cylindrical design allows the unit to easily shed rain, snow, ice and dirt. The single piece cover design provides added protection against leakage under extreme conditions. High and Low Frequency Pulser Options: The Counter with Electronic Transmitter (ICEX) provides a high frequency non-compensated pulse output for applications requiring information on the gas flow rate while the low frequency solid state pulsers are a lower cost option for both non-compensated (ICPWX) and temperature compensated (ITPWX) volume accumulation applications. Non-Moving Odometer Masking System: A unique and versatile odometer masking design using opaque or semi-transparent covers offers configurable, trouble-free masking. Universal Instrument Drive (ID) Assembly: One size fits all with the Series Instrument Drive Assembly. Inventory costs are reduced by stocking one ID Assembly. AMR Adapter: The new direct drive AMR Adapter offers you a low cost solution for Series B CTR or TC meters in applications that require the adaptation of a Residential ERT or Cellnet AMR. The AMR Adapter is available as a conversion kit for field installation or factory installed on new meters.

36 General Information The Series B ROOTS meter is a positive displacement, rotary type gas meter designed for continuously measuring and indicating the accurate measurement of gas. ROOTS meters are suitable for handling most types of clean, dry, common gases at either constant or varying flow rates. Meters of standard construction are not directly suitable for handling acetylene, biogas or sewage gas. Contact the factory for information on specially constructed meters made of materials more compatible with these and other gases. Volumetric accuracy of the ROOTS meter is permanent, non-adjustable, and is not affected by low or varying line pressure. Series B meters may be used satisfactorily for pressures ranging from a few ounces to full Maximum Allowable Operating Pressure (MAOP). Displaced volume measurement is completely independent of the gas specific gravity, temperature, and pressure. Series B ROOTS meters have a MAOP rating of 75 psig (00kPa). Every meter is static pressure tested at the factory at twice its MAOP and leak tested at 5 percent of MAOP in accordance with ASME Boiler Pressure Vessel Codes. Other pressure ratings are available. Consult Factory. ROOTS meters are manufactured in accordance with ANSI B09. for Rotary Type Gas Displacement Meters. Series B ROOTS meter sizes 8C through 56M, have flanged inlet and outlet connections conforming dimensionally with ANSI/ASME standards. Sizes 8C through M are available with -/ NPT connections, upon special request. The meter operating temperature range is from -40 F to +40 F (-40 C to +60 C) while the temperature compensating mechanism of the TC accessory provides a corrected reading for temperatures ranging from -0 F to +0 F (-9 C to +49 C). Series B ROOTS meter bodies accept a wide range of Series accessories for all metering applications. AMR Adapters for Series B ROOTS Meter.
