2. application fields
Waterpilot FMX21 is a kind of static pressure gauge, Endress+Hauser offer 3 different kinds of structures type of Waterpilot FMX21:
Stainless steel shell, outer diameter is 22 mm (0.87 in)的FMX21:standard, adapting for measuring the static pressure level of drinking water/Pumping Wells, deep Wells and other small diameter places.
Stainless steel shell, outer diameter is 42mm(1.66 in) FMX21: heavy type, Flush diaphragm installation, easy to clear, it is the best solution for measuring the medium of Waste water and sewage treatment plant
Adopting coating case, outer diameter is 29 mm (1.15 in) FMX21: Type, strong corrosion resistance, applicable seawater and the ship equipment (e.g., water ballast tank) mediation qualitative static pressure level measurement
