Electronic Temperature Volume Compensation (ETVC) Installation
When ordered as part of a meter system with a LCR 600, the ETVC kit is bolted onto the strainer and wired to the LCR 600 at the factory. ETVC 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-inch 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 the Warnings in Mounting Overview.
2.Remove the old strainer cover.
3.Clean the strainer basket and replace it into the housing.
4.Lightly coat the new cover gasket (included with the ETVC kit) with lubricant. DO NOT use the included copper grease.
5.Fit the new cover gasket into the 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 Thermowell kit.
8.Coat the entire probe length with the copper grease provided. Insert and recoat the probe 2 or 3 times to provide a uniform coating inside the Thermowell 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 above.
10.Connect the conduit to a ½" 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 J14.
