Plastic Flowmeter and Switch Model KSM

Description

The KSM series plastic flowmeters are an excellent choice
for applications measuring aggressive media. There are no
metal parts in contact with the fluid. The measuring tubes are
Trogamid-T® or Polysulfone, with other wetted parts made
of PVDF, PVC and EPDM. The standard flow meters are
equipped with a scale for water or air and a percentage
scale. It has two adjustable markers, a rail for accessory
switces, and a PVC glue or NPT connection with capnut.
A Polysulfone measuring tube is available for very corrosive
media and a Trogamid-T® tube is available for less aggressive
media. Both options are rugged and shock resistant.
