The HLM series Hydrostatic level transmitters are compact measuring devices containing silicon tenzometric sensor and measuring electronics in a stainless housing. The transmitter housing is fitted with a 2 or 3 wire signal/power cable with capillary (for comparing atmospheric pressure into probe).
Hydrostatic level transmitters are intended for continuous level measurement of relatively clean, non-aggressive liquids in non-pressurised reservoirs, drill holes, water wells, sumps, tanks and swimming-pools.
