Turbine Flow Meter

Category - Flow Sensing

Project Description

Scharf Automation Turbine Flow Meter or Digital Water Meter is employed for fluid flow measurement in clear liquids. It is also used in gases in general industrial applications for volumetric flow measurement. Turbine Flow meter's performance is outstanding when accuracy, quality & consistency in operation is concerned.

Working
The flowing media imparts a force on the turbine (rotor) placed in-line, which thereby spins at an angular velocity. This angular velocity is in direct proportion to the flow rate. This velocity is sensed by the sensor and converted to a digital signal by electronic front end inside the instrument. Finally, this digital signal is converted to flow rate to display it on the screen onboard. The on-board flow computer designed by Scharf Automation Engineering team, calculates and displays the flow-rate as well as totalized value of liquid or gas that has passed through the meter via pipeline with an amazing accuracy of 1%. On request, we even provide an accuracy of 0.5% and we always strive to achieve better than that.

Important Tips
Electro-magnetic flow meters suffer from the drawback that the flowing media or liquid must be conductive in nature, whereas such is not the case with Turbine Flow meter, which provides excellent performance even in non-conductive liquids like kerosene, petroleum, vegetable oil etc.
It is well known that Turbine Flow meter provide excellent performance only when working under High flow rates. Hence for Low flow rate measurements, either Metal Tube Rotameter (click here) OR Glass Tube Rotameter (click here) is recommended.
