Vortex Gas Flowmeter for Process Measurement

  1. 1. The MVF series of Micro Flow vortex gas flowmeters make use of our proprietary μF (Micro Flow) sensor, which has high sensitivity and quick response. As a result, MVF flowmeters achieve a wide measurement range of 100:1. In addition, a temperature and pressure compensation function is built in, so there is no need for a temperature sensor, pressure sensor, or compensation device, contributing to the reduction in total cost.
