Flow switch with flow indicator
0.4 - 133 l/min, 4 - 20 mA | LIQUI-VIEW Mass Flow ONLINE BV

The LIQUI-VIEW series offer a compact, light weight and cost-effective solution for monitoring the flow or consumption of cleansing, cooling or spa water. The unique sensor body and transmitter design makes LIQUI-VIEW one of the most compact, lightweight vortex meters in the industry.
The LIQUI-VIEW offers an easy-to-read digital display and has integrated totaliser and alarm functions. The LIQUI-VIEW series operate on the vortex principle. The obstruction (bluff body) placed in the flow of the liquid sheds vortices downstream at a frequency proportional to the velocity of the liquid. This pattern of vortices is named the Von Kármán vortex street. A piezo-electric sensor detects the vortices and creates electrical pulses which are proportional to the liquid flow rate. The instruments may be mounted in any position; the local read-out unit can be rotated. LIQUI-VIEW flow meters can be supplied in full scale ranges from 4 l/min up to 133 l/min at max. 10 bar pressure rating. An LCD display allows reading of actual flow and two total flow indicators with one reset switch. Furthermore the instruments can be supplied with an analog output or with two alarm outputs, thereby operating as a flow switch.
