glass Level gauge control for steam boiler
Glass plate type liquid level gauges include transparent type level gauges, reflective type level gauges, defrost type level gauges and sight glass level gauges.
Lead fluid in tank to outer to sight glass level gauge based on the communicator theory. And they show the actual liquid level directly through the transparent glass.
Sight Glass type Level Gauges select flexible graphite plunger ring as gasket to assure seal ability.
Directly reading, can assure the reading accuracy and reliable service.
Simple structure and convenient maintenance.
Safety in use and long time in service.
