Seametrics Low-Flow Impeller Sensors

Impeller design minimizes wear for long sensor life
  • Utilizes rotating turbine and a magnetic Hall-effect sensors
Each flow sensor uses a rotating turbine and a magnetic Hall-effect sensor to generate an electronic pulse proportional to flow rate. The controller converts these pulses into flow units. These low-flow sensors measure flow rates in pipe sizes from 3/8 to 1" NPT(F). Sensors generate a square wave pulse output that can be sent to flow controllers 33110-60 or -70 to display flow rate and total, batch controller 33112-52 which provides batch output control to multiple devices, or rate/total display 33112-50, which is a battery operated two-line display.

Choose from polypropylene (PP), PTFE, 316 stainless steel (SS), or brass sensors. Select PP sensors for general-purpose applications. Use PTFE sensors for high-purity, high-temperature applications. The 316 SS sensors should be used in applications such as chemical batching and injection, fertilizer injection, or proportioning of spray chemicals. Brass sensor should be used in applications using clean water. For best results, install sensors within a straight run of tubing or pipe (five pipe diameters long on the inlet side). Sensors can be mounted in any orientation. All models include an 18-ft (5.5-m) L cable with stripped ends.
