Mass-Flow ONLINE LIQUI-VIEW Base series of vortex flowmeters

Mass Flow ONLINE has introduced updated models of its LIQUI-VIEW Base series of vortex flowmeters. The models are now equipped with a bright, wide-angle and easy-to-read display for local readout purposes. As the working principle of the instrument allows it to be mounted in any position, the structural design of the display makes it possible to rotate it through 180°. Besides a local readout, the models also offer 4–20 mA output signals.

The obstruction (bluff body) placed in the flow of the liquid sheds vortices downstream at a frequency proportional to the velocity of the liquid. A piezoelectric sensor detects the vortices and creates electrical pulses which are proportional to the liquid flow rate. The instruments can be mounted in any position and can be supplied in full-scale ranges from 10 up to 150 L/min at a maximum 12 bar pressure rating.

The instruments are suitable for monitoring the flow or consumption of cleaning or cooling water and have an IP65 protection rating.
