Liquid Level Transmitter

Product Bulletin 61-60

Purpose:

HBLT capacitive liquid level 

transmitters are used to measure 

liquid levels in refrigerant vessels, 

receivers, accumulators, or other 

similar pressure vessels.  Available in 

various lengths and factory calibrated 

for ammonia (R717).

Product Features:

• 

Suitable for ammonia, CO

2

 and 

halocarbon refrigerants 

•
