3 Model 351/352/353 Liquid Level Systems Section 1 Section 1 Introduction General The Barton Liquid Level System provides accurate hydraulic transmission of a process medium for measuring the level of liquids contained in a process vessel. The self-contained system is typically mounted outside the vessel. Floats, levers, pins, and other mechanical devices susceptible to contamination or wear are not required. Because the basic system is actuated by the process media, local indication is possible without external power. Barton Liquid Level Sensors can be purchased as a component of a factorybuilt system, or as a part for a field-installed system. Sealed sensor systems can be designed in the following configurations: a single sensor system (Model 351) a dual-sensor system (Model 352) For applications involving corrosive fluids or tank temperatures above 200 F (95 C), a dual-sensor configuration is recommended. For applications involving unusual fill requirements due to liquid volumes or high ambient temperatures, a Model 353 system is recommended. The Model 353 system can be designed with one or two sensors. See Model 353 Liquid Level System on page 5 for details. Process vessel Single sensor Sensor DPU (shown with indicator) Sensor Single-Sensor System Dual-Sensor System Figure 1.1 Single-sensor and dual-sensor system configurations IMPORTANT: In this manual, the term sensor, refers to a mechanical bellows assembly and its pressure housing used to detect and transmit a hydraulic or pneumatic signal to an electronic transmitter, mechanical indicator or switch. 3

4 Section 1 Model 351/352/353 Liquid Level Systems Product Description Model 351 Liquid Level System The Model 351 consists of a single reference sensor connected by capillary tubing to a Barton Differential Pressure Unit (DPU). Hydraulic fluid is sealed inside the sensor and the capillary tubing, eliminating the need for additional piping. The Model 351 system, as shipped from the factory, needs only to be mounted on the vessel to provide continuous level measurement when used with a Barton readout instrument. The sensor can be installed on vented or sealed process vessels. The readout instrument (DPU, for example) can be installed at various elevations (i.e., below the vessel, at the vessel upper connection or above the vessel ) as long as the instrument calibration considers the elevation difference between the instrument and the sensor. Model 352 Liquid Level System The Model 352 consists of two reference sensors connected by capillary tubing to a Barton DPU. Unlike the Model 351 system, the process media does not come into contact with the DPU, making the model ideal for applications involving corrosive liquids or tank temperatures above 200 F (95 C). The DPU can be mounted up to 50 ft (15 meters) away from the vented or sealed process vessel and at ele vations up to 30 ft (9 meters) above the lowest sensor. Elevation of the readout instrument (DPU) with respect to the sensors is essentially unlimited as long as the instrument calibration considers the elevation difference between the two sensors. Model 351/352 System Sensors A Model 351 or Model 352 system can include any of three sensor types, depending on the pressure rating required: 500-psi SWP sensor (referred to as Model 351 sensor throughout this document) 3,000-psi SWP sensor (referred to as Model 351 sensor throughout this document) No-pressure-rating sensor (referred to as Model S048 sensor throughout this document) All three sensor types contain a 3.75 (95 mm) bellows that functions as a seal. As pressure on the bellows varies due to changes in liquid level and/or process system pressure variations, these pressure variations are transmitted through the liquid filled sensor and capillary tubing to the readout instrument. 4

5 Model 351/352/353 Liquid Level Systems Section 1 The S048 sensor is constructed with the same housing as the 500-psi SWP sensor for mounting purposes, but has no pressure rating and is designed to mount inside open ves sels or sumps. The large bottom opening of the sensor prevents fouling of the sensor ports due to dirt, loose debris, or other contamination. Model 353 Liquid Level System The Model 353 system is designed specifically for unusual fill liquid requirements due to liquid volumes or high ambient temperatures. A Model 353 system can be designed with one or two sensors. Systems are typically assembled in the field. The Model 353 high-volume sealed sensor is rated for a 3,000-psi SWP and contains a single removable bellows with an initial volume of 10 in.³ (164 cc). The bellows is 2.25 in. (57 mm) long and has a diameter of 3.75 in. (95 mm). It can extend an additional 1 in. (25 mm), adding an additional 7.5 in.³ (123 cc) to its volumetric capacity (see Figure 1.2). When the bellows is fully compressed, an internal valve closes to prevent the escape of process fluids. The bellows may be removed for replacing a dam aged bellows or for pressure testing the capillary tubing. Travel to close valve 0.84 in. (21 mm) Normal length 2.25 in. (57 mm) 1 in. (25 mm) Expanded bellows (hot condition) Figure 1.2 Model 353 bellows travel (approximate dimensions) Sensor Housings and Capillary Tubing All sensors have stainless steel housings. Capillary tubing connecting the sensor to the DPU is either 1/4-in. or 3/16-in. OD. Tubing length is deter mined by the installation. Capillary tubing may be bent or looped as required. A 1/4-in. NPT plug or a high-pressure fitting (3/8-in. OD tubing) in the housing facilitates venting. 5

6 Section 1 Model 351/352/353 Liquid Level Systems Specifications Specifications for Barton sealed sensor systems are presented in Tables 1.1 and 1.2. CAUTION: Never operate the system at pressures exceeding the safe working pressure of the sensor flange or attached instrument, whichever is lower. Periodic testing at pressures up to 150% of the safe working pressure is permitted, provided the pressure is applied equally and simultaneously to the entire system.

7 Model 351/352/353 Liquid Level Systems Section 2 Section 2 Theory of Operation General A fluid column exerts a pressure proportional to its height and density, independent of the shape or volume of the containing vessel. A differential pressure unit (DPU) can be calibrated to indicate the height of a fluid when the fluid density is known. In tanks of given dimensions, the weight and volume of contents can be measured by a DPU. One or two sealed sensors are connected to the DPU by capillary tubing. These sensors contain bellows which function as isolation seals. As pressure on the sensor bellows varies due to changes in liquid level, the variations are transmitted hydraulically through the tubing to the bellows of the DPU. Model 351/Model S048 Sensors The pressure deflection characteristics of the Model 351 (500-psi or 3,000- psi) and Model S048 sensor bellows are shown in Figure 2.1. Figure 2.1 Pressure deflection characteristics of the Model 351/352 sensor bellows Model 353 Sensor In the event of thermal expansion of the fill-liquid in the capillary tubing and in the other instruments, the Model 353 sensor bellows can extend 1 in. (25 mm) for 7.5 in.³ (123 cc) displacement. If leakage occurs in the capillary tubing, the bel lows becomes compressed approximately 0.56 in. (14 mm) and 7

8 Section 2 Model 351/352/353 Liquid Level Systems then closes an internal valve to prevent further loss of bel lows liquid. This action prevents escape of process liquid. The sensor bellows may be removed with a special wrench (see Table 4.1 and Figure 4.1, page 14). This permits pressure testing and leak testing of the housing and capillary tubing and allows damaged parts to be replaced before the system is filled. The pressure deflection characteristics of the Model 353 sensor bellows are shown in Figure in. (25 mm) Normal length 2.25 in. (57 mm) Travel to fully close valve 0.84 in. (21 mm) Figure 2.2 Pressure deflection characteristics of the Model 353 sensor bellows The bellows can extend over 1 in. (25 mm) to accommodate fill fluid expansion under hot operating conditions. As seen in Figure 2.2, the expansion creates an internal pressure of 25.7 in. H2O (6.4 kpa) at 1 in. (25 mm). When compressed, the bellows travels approximately 0.5 in. (13 mm) before the internal valve begins to close. Compression of the bellows to 0.5 in. (13 mm) requires approximately 10 in. H2O (2.6 kpa) of external pressure. 8

9 Model 351/352/353 Liquid Level Systems Section 3 Section 3 Installation Unpacking All instruments are inspected during manufacture and prior to shipping. However, an inspection should be performed at the time of unpacking to detect any damage that may have occurred during shipping. When unpacking, carefully remove the instrument from the container. If the instrument is a liquid-filled sys tem, remove the strap-fasteners and gently unroll the capillary tubing. The transmitter output may indicate Near Full Scale if the system is tested prior to installation. This is nor mal, and the transmitter output will be correct when the reference leg is elevated. Model 353 Sensor Assembly The Model 353 sensor bellows and bottom plate bolts are not torqued to installation requirements as shipped. See Section 4 on page 13 for instructions on removal and replacement of Model 353 sensor bellows. Mounting Mount the sensors as close to vertical orientation as possible to ensure proper operation. The sensor may be oriented with the vent pointed up or down, depending on the service or installation design. When mounted with the L-bracket, mount the sensors with three 3/8-16 SAE bolts, Grade 5 or better, torqued to 24 to 26 ft-lb (33-35 N-m). The mounting bracket may be rotated axially or reversed, as required for installation (as shown in dimensional drawings in Section 6). Interfacing process tubing should be supported to minimize relative motion between the sensor and connections. The capillary tubing should be supported with at least one support located within 1 ft (0.3 meters) of the sensor. The minimum bend radius of the capillary tubing is 2 in. (50 mm). Piping and Installation IMPORTANT: Sealed systems are normally filled at the factory, but can be installed and filled in the field. Sensors should be connected in accordance with user specifications. Flanges and tube fittings (3/8, 1/2 or 3/4 ) are available for this purpose. 9

13 Model 351/352/353 Liquid Level Systems Section 3 Section 4 Operation, Maintenance, and Calibration Startup Startup and operating instructions for an instrument actuated by the Liquid Level System are presented in the installation and operation manual for that instrument. General Field and Periodic Maintenance The sensor is basically maintenance-free. If installed in an application where sediment can accumulate in the bel lows convolutions, periodic inspection and cleaning may be required. CAUTION: The sensor bellows can be damaged by contact with the housing. When removing the sensor assembly, avoid unnecessary contact with the housing. Model 351 Sensor Inspection and Cleaning 1. Remove the sensor from the housing. The 500 psi (3.5 MPa) sensor is connected by a retainer ring; the 3000 psi (20.7 MPa) sensor is connected by 6 bolts. Carefully separate the sensor from the housing assembly. 2. Remove any accumulated material from between the bellows convolutions, using a soft brush and solvent as required. 3. Inspect the O-rings and seals before reassembly. Replace as necessary (see note on page 17). 4. Replace the housing over the sensor bellows. For 3000 psi (20.7 MPa) sensors, lubricate the bolt threads and seat the bolts at 34 to 35 ft-lb (46 to 48 N-m). For 500 psi (3.5 MPa) sensors, install the retaining ring. Model 353 Sensor Inspection and Cleaning 1. Remove the 12 bolts connecting the sensor to the housing, and carefully separate the sensor from the housing assembly. 2. Remove any accumulated material from between the bellows convolutions, using a soft brush and solvent as required. 3. Inspect the bellows for damage. Free-length should be 2-1/4 in. (57 mm) (see Figure 1.2). Length may vary by 1/8 in. (3 mm) due to system temperature-effects. Press lightly (by hand) on the free end of the bellows; the bellows should be incom pressible if the system is liquid filled. 4. Inspect the O-ring, backup ring, and nickel gasket before reassembly. Replace as necessary (see note on page 17). 5. Carefully replace the sensor in the housing assembly. Lubricate the bolts lightly and torque uniformly to approximately 34 to 35 ft-lb (46 to 48 N-m). 13

14 Section 3 Model 351/352/353 Liquid Level Systems Model 353 Sensor Bellows Removal/Replacement The sensor bellows must be removed under the following circumstances: when the capillary system is to be pressurized for argon flow during weld ing for static pressure tests of the capillary system for replacement of a damaged sensor To remove the sensor bellows, perform the following steps: 1. Remove the 12 housing bolts. Carefully remove the bellows bottom plate assembly from the housing. CAUTION: The sensor bellows can be damaged by contact with the housing. When removing the sensor assembly, avoid unnecessary contact with the housing. 2. Remove the bellows from the bottom plate by turning the valve seat with the sensor bellows wrench and lift ing the bellows until the guide stem is withdrawn from the capillary tubing. Observe the two O-rings on the bottom of the valve seat; they may fall free when the bellows is lifted. 3. (Pressure Tests Only) Install a test fitting with an O-ring (refer to Figure 4.1, item 4, and Figure 4.2, page 15). Tighten with the sensor bellows wrench to 39 to 40 ft-lb (53 to 55 N-m). Remove the test fitting when pressure tests are complete.

15 Model 351/352/353 Liquid Level Systems Section 4 Figure 4.2 Model 353 sensor bellows and bottom plate assembly To install the sensor bellows, perform the following steps: 4. Inspect the sensor bellows to verify that the bellows is undamaged and the guide stem is in place. IMPORTANT: This inspection should be performed whether the old bellows or a replacement bellows is to be installed. 5. Inspect the two O-rings in the valve seat, the O-ring and the backup ring in the bottom plate, and the nickel gasket to verify there is no damage (see note on page 17). Install the nickel gasket on the bottom plate. Lubricate the O-rings and backup ring lightly with lubricant (part number 9A-C U) and insert in the appropriate grooves. 6. Engage the valve seat to the bottom plate. The guide stem must enter the capillary tubing without restric tion. IMPORTANT: To prevent loss of the O-rings in the valve seat, invert the bellows and bottom plate during this step. 7. Tighten the valve seat with the sensor bellows wrench to approximately 39 to 40 ft-lb (53 to 55 N-m). Verify that a metal-to-metal fit is obtained between the valve seat and the bottom plate (zero clearance). 8. After the sensor bellows and capillary tubing are filled with liquid, carefully insert the plate and bellows assembly into the housing. Uniformly tighten the 12 housing bolts to 34 to 35 ft-lb (46 to 48 N-m). 15

16 Section 4 Model 351/352/353 Liquid Level Systems CAUTION: The sensor bellows can be damaged by contact with the housing. When installing the sensor assembly, avoid unnecessary contact with the housing. Calibration The actuated instrument is calibrated according to the procedure presented in the installation and operation manual for that instrument. IMPORTANT: During calibration, the sensor should be elevated to the exact position it will occupy in the installa tion. Otherwise, calibration pressures must be modified to compensate for the differences in hydro static pressures.
