ABOUT MICRONICS LTD
Since its inception Micronics has sold clamp-on water meters in more than 50 countries, concentrating mainly on portable “Time of Flight” meters, some of which are marketed under the registered trade name of Portaflow™.
From the introduction of the first portable instrument the company now markets a range of 13 different products incorporating “Time of Flight” or “Doppler” technology. The range includes portable instruments and fixed meters based on the use of non-invasive ultrasonic sound transmission to detect liquid flow velocity within closed pipes or open channels. There are Energy options for clamp-on fixed meters, tank and level meters are also available.
Micronics are specialists in Ultrasonic Liquid Flow Meters with a tradition of innovation and a well-established world position.
