Flow Measurement

Flow and pressure instruments measure liquid flow in pipes and pressure in air, gas and liquid systems. The range includes portable, clamp-on, insertion and Doppler ultrasonic flow meters, electromagnetic and oval gear flow meters, digital pressure gauges and differential pressure manometers.

Typical applications

• Flow checks on water and process pipes without cutting the pipe
• Permanent flow monitoring
• Pump and system performance checks
• HVAC and filter differential pressure measurement
• Pressure testing and verification

Choosing an instrument

Key factors are the liquid and whether it is clean or carries solids or bubbles, the pipe material and diameter, whether the meter must be portable or permanently installed, the flow or pressure range, and the outputs or logging required.
