FLRT-11-RLVT is used for measurement and recording of water flow through dam discharge.
It is also installed to measure and record flow thru open channels, streams & rivers.
Can be used as Flow Data Logger cum RTU with Wireless Data Acquisition system.


When FLRT-11-RLVT flow meter is installed across open canal or stream, it can measure, calculate & totalize the flow based on one of the two following principles-
Programmed formulas for different dimensions of the most common flumes and weirs such as Cut Throat, Parshall flumes and V-notch weirs based on ISO 1438.
In case of Flow measurement on the basis of Area Velocity calculation, Input range can be programmed in nonlinear scale up to 100 steps.
