Portable Ultrasonic Flowmeter PLUT

Handheld type ultrasonic flow meter consists of a flow transmitter and a clamp-on transducer. With the latest electronics and the digital signal processing technology. Using ultrasonic transit time techniques, handheld ultrasonic flow meter is controlled by a micro-processor system which contains a wide range of data that enables it to be used with pipes with an outside diameter ranging from 15mm up to 6000mm and constructed of almost any material. The instrument will also operate over a wide range of fluid temperatures.


Clamp-on type sensor easily mountable on existing pipe Suited for a wide range of liquids, for example, deionized water, cooling water, chemical solution, drinking water, sea water, oil, tap water, hot water, industrial water, corrosive liquids.
