Waste water Level sensors with open face flush diaphragms for measuring the hydrostatic pressure of sewage and effluent waste.
Waste water such as sewage will block pressure ports in a similar way as viscous media and flush diaphragm hydrostatic level sensors are preferred to reduce the potential for clogging and make cleaning easier.
Due to the presence and potential build up of flammable gases from sewage it is required in some countries to use intrinsically safe hydrostatic level sensors in waste water treatment works.
Select a level sensor for mounting inside or external to a tank or sewage pipe.
