Submerged Area Velocity Sensor

Submerged Area Velocity Sensor
Series: SUB AV
Unit Price Contact McCrometer

Single-point calibration

Ability to calibrate the sensor and adjust it to read accurately at one specific value of the parameter being measured, also known as a “single known reference point”; this helps to measure flow rate, pressure, or temperature.

Robust Sensor

The sensor can withstand conditions such as harsh chemicals, extreme temperatures, high flow velocities, and abrasive or corrosive materials without degrading in accuracy or requiring frequent maintenance.

Streamlined Design

Sleek and efficient physical configuration that minimizes obstructions to fluid flow, reducing pressure loss and turbulence within the system.

Minimal Sensor Fouling

Oil-filled Submerged AV sensor models are great solution for monitoring sites that are susceptible to fouling of the pressure transducer. The cavity is filled with high-viscosity silicon oil to reduce the collection of sand, silt and grit on the pressure transducer. Use the non-oil-filled cover plate model in sites where the pipe could run dry. Either way, we’ve thought about the little details that will reduce your maintenance or lost data hassles.
