Pulsar Measurement, Trading Name of Greyline Ultrasonic Flow Meters

Ultrasonic flow meters use sound waves as a reliable, accurate and maintenance free method to measure the velocity of a fluid from which the volumetric flow rate can be calculated. They feature no moving parts making them more reliable and accurate while providing maintenance-free operation.
