Seametrics SES Stainless Steel Single Jet Flowmeter

The SES single-jet meter provides accurate, wide range flow metering in an extremely rugged stainless steel package.


The SES single-jet meter provides accurate, wide range flow metering in an extremely rugged stainless steel package. Single-jet simplicity combined with high quality jewel bearings results in long life and relatively high tolerance for problem fluids. Typical applications are chemical batching, proportional chemical injection, fertilizer injection, proportioning of spray chemicals, and general flow rate monitoring.
The sensor is easily replaced from outside the meter, and is compatible with most of the Seametrics indicators and transmitters, as well as most controls and PLC’s that accept DC inputs. The standard rotor is PVDF (Kynar®) and the shaft is a special nickel-bonded tungsten carbide. The optional ceramic shaft increases resistance to some concentrated chemicals. The standard O-ring is Teflon®-coated Viton®.
