Liquid Level Sensor - HFC, HFO & CFC

Technical data: HBLC-HFC

The HBLC-HFC sensor is specifically designed for measuring HFC, HFO, and CFC refrigerant levels in chillers, evaporators, or condensers - and transmits this information via a 4-20 mA analog signal. Although pre-configured for R134, it can be adjusted to detect other types of HFC, HFO, or CFC refrigerants.
