ETVC Wiring
To install the eTvC kit:
1. Depressurize the meter completely. See Warning 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
ETVC 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 thermowell 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 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.
10. Connect the conduit to a ½" NPT port on the back of the
LCR-II using the elbow fittings provided with the conduit
kit (PN 81024).
11. Wire the temperature probe to the LCR-II internal board
on connector J14.
Disconnect the power before
working on the CPU board.

electronic Temperature volume Compensation (eTvC) Installation
When ordered as part of a meter system with a LCR-II, the ETVC kit is bolted onto the strainer and wired to the LCR-II
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" 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-II.
