merican Meter Series and Worker/Monitor Regulators Worker/Monitor sets are commonly used to provide overpressure protection. 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 Series Monitor onversion merican Meter offers four industrial monitor regulators the M, M, 88M and 8M. esign improvements now enable all models to be configured as Monitor Regulators. This change was effective with all and Series Regulators manufactured after January 99. The advantage is that two models of the same regulator need not be stocked. ll models are pre-machined to accept a monitor conversion kit. Refer to IMP 87 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.

Springs The Series spring ranges from.5" w.c. to 5 outlet pressure. Series spring ranges from / to 5 outlet pressure. See page. Interchangeable Orifice vailable in sizes from /" through -/" 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.

UPSO Snap-acting lever for underpressure shutoff protection when line pressure drops drastically.
merican Meter Regulators Other Features 8 Partial Relief Series low-pressure models have a maximum inlet pressure of 5 and offer outlet pressures ranging from.5" w.c. to 5. Series high pressure models allow a maximum inlet pressure of 5 and outlet pressures ranging from.5 to 5. The Series can be ordered as Full Relief, Partial Relief or No Relief Regulator as shown in the table. Series Regulators are non-relieving. oth models are available with Overpressure Shutoff, Underpressure Shutoff and monitor capabilities. Low Pres.

merican Meter UPSO OPSO OUPSO Regulator Safety Features vailable Exclusively From merican Meter On Series and Industrial Regulators Pressure control and automatic shutoff devices for the protection of public buildings, schools, theaters, hospitals, etc. are available in one complete package on several and Series Industrial Regulator models (see page 5). Installing one of these regulators provides automatic protection against possible extreme variations in either inlet or outlet gas pressure. UPSO The UPSO (underpressure shutoff) models provide complete shutoff protection in case of severely interrupted inlet gas pressure. If the inlet or outlet pressure is severely interrupted, causing the regulator to stroke to a full-open position, the shutoff closes, providing complete system safety. The shutoff valve remains closed until manually reset. How The UPSO Operates When gas pressure under the main diaphragm falls below normal, the shutoff device is tripped and the spring, connected with the valve plunger, forces the valve seat against the orifice closing off gas flow. The UPSO must be manually reset to re-establish gas flow. Figure To reset the underpressure shutoff device (Figure ), unscrew the reset plug with a wrench. When it becomes free of the threads, pull it out until it engages the reset mechanism. With the wrench, turn the reset shaft clockwise until the reset mechanism is engaged. Hold firmly in this position until normal pressure is established under the diaphragm and downstream line, and regulator operation is restored. Screw in the reset plug and tighten. Overpressure Shutoff (OPSO) in cocked position Overpressure Shutoff (OPSO) in tripped position OPSO Overpressure shutoff regulator models prevent excessive gas pressure from entering a building causing a hazardous condition. The shutoff device closes if the regulator outlet pressure rises above a maximum set point or set pressure. How The OPSO Operates When line or static pressure increases to the specified overpressure shutoff setting, the pressure on the under side of the shutoff diaphragm over-balances the spring, forcing the diaphragm stem outward, releasing the plunger. This permits the shutoff spring to force the shutoff disc against the orifice, closing off gas flow. The OPSO assembly is part of the regulator but is not connected to the regulator operating mechanism. When selecting a shutoff spring, a minimum differential of " w.c. between normal operating pressures and the shutoff pressure setting should be provided. To reset the overpressure shutoff device, unscrew the seal cap, which opens the regulator orifice, permitting gas flow. Pull out on the seal cap until the overpressure shutoff device latches completely. Tighten the seal cap. o not trip the shutoff valve unless the seal cap is installed. OUPSO Overpressure and underpressure shutoff models combine both safety features for maximum protection. On these models, when the OPSO shuts off, the UPSO automatically trips, providing double assurance of positive gas shutoff. The overpressure shutoff device must be reset first followed by resetting the underpressure shutoff device. 5
