ETVC INSTALLATION Electronic Temperature Volume Compensation (ETVC) Installation When ordered as part of a meter system with a LCR 600, the ENC kit is bolted onto the strainer and wired to the LCR 600 at the factory. ENC kits can also be ordered and retrofit onto meter systems already in service. Although there are several installation kits—kits are specified according to meter size and application—they are all installed in the same manner. A conduit kit (PN 81024), with a 30" length of weatherproof flexible conduit, is available from Liquid Controls to provide protection for the RTD temperature probe wire between the strainer cover and the LCR 600. To install the ETVC kit: 1. Depressurize the meter completely. See Mming on pg. 14. 2. Remove the old strainer cover. 3. Clean the strainer basket and put it back in the housing. 4. Lightly coat the new cover gasket (included with the ENC kit) with lubricatant (do not use the included copper grease). 5. Fit the new cover gasket into strainer cover groove. 6. Bolt the strainer cover in place. Make sure the Weights & Measures thermowell port is at the top of the cover. 7. Assemble the thennowell kit (see Thermowell Kit figure on the left). 8. Coat the entire probe length with the copper grease provided. Insert and re -coat the probe 2 or 3 times to provide a uniform coating inside the thennowell and to ensure proper heat transfer from the liquid to the probe. 9. Connect the assembled thermowell to the fitting in the middle of the strainer cover. The angled fitting at the top of the cover is for Weights & Measures purposes. See Step 6. 10. Connect the conduit to a YV NPT port on the back of the LCR 600 using the elbow fittings provided with the conduit kit (PN 81024). 11. Wire the temperature probe to the LCR 600 internal board on connector A4. I . . ..

Electronic control valves can also be ordered separately and retrofit onto meter systems already in service. These valves will need to be piped and wired in the field. For piping instructions, refer to the valve manual. This manual includes wiring instructions for the valves. In order to control flow, the LCR 600 energizes and de -energizes solenoid -operated valves on external bypass piping routed off the main product flow. The solenoid operated valves close off and open the bypass pipes. The bypass pipes redirect some of the product flow in order to open and close the control valve. These solenoid -operated valves must be wired to the LCR 600 CPU board during installation. Liquid Controls offers single stage and two stage electronic valves. Single stage valves have one solenoid valve (S1) and two positions—an open position and a closed position. Two stage valves have two solenoid valves (S1 & S2) and three positions—open, closed, and dwell flow. Dwell flow is a low flow rate setting controlled by the S2 solenoid and initiated shortly before the register reaches a preset value. SINGLE STAGE VALVES The three most common Liquid Controls meter systems with single stage valves include a block valve with a S1 solenoid -operated valve fitted onto external piping (A2847-11), a block valve (A2843) with a i-way solenoid, and an electro-pnuematic valve with an S1 solenoid. A2847-11 Valve This single stage control valve has a S1 solenoid - operated valve located at the meeting point of three pipes: one pipe from the inlet side of the valve, one from the top of the block valve, and one from the outlet side of the valve. This valve is typically used in refined fuels applications. A2843 Valve and 3 -Way Solenoid The 3 -way solenoid -operated valve --mounted directly to the top center port on the back of the LectroCount LCR 600—serves as a S1 solenoid -operated valve. The 3 -way solenoid -operated valve is located at the meeting point of two pipes from the vapor eliminator (one for eliminated vapor and one leading to the spit tank) and one pipe to the top of the block valve. 3 -way solenoid - operated valves are typically specified for products that hold vapor in the line such as LPG and NH3. 19 L] [gin Rd 23 3 1 � _�'fiis6as[ TEAPE.H11.11i Al it A2847-11 Solenoid -Operated Block Valve A2859-11 Block Valve and 3 Way Solenoid (PN 81527) Electro-Pnuematic Preset Valve Single Stage Electro-Pnuematic Valve with V-7 Valve VALVES Liquid Controls' Valves Overview When ordered as part of a meter system with a LCR 600, Liquid Control's control valves are bolted onto the meter and wired to the LCR 600 at the factory.
