More About this Item

Flow indicators feature a paddle-wheel that spins at a rate proportional to the flow. Lens can be removed with a 1/4 turn for easy cleaning. Use with fluids that have a viscosity less than 34 centipoise (150 µm filter is r ecommended for protection).

Indicators/Sensors feature a Hall-effect sensor that produces a 4.5 to 24 VDC pulse output. Maximum current source output is 70 mA, and frequency output range is approximately 25 Hz at low flow to 225 Hz at high flow.

Indicators/Switches offer extra level of reliability and protection with a built-in switch. Each Single Pole Double Throw (SPDT) switch is rated for 1 amp, 24 VDC resistive. Repeatability is ±2% ; accuracy is ±5%. An LED lights when the set point is reached for easy field calibration.
