Flow Meter

  • Electromagnetic Flow Meter
    The electromagnetic flow meter accurately measures the flow rate of any conducting liquid or slurry that is flowing in closed pipes. It is obstruction less and hence offers no pressure drop in the process. Absence of moving parts ensures that there is no need for maintenance. The performance of the

  • Glass Tube Rotameter

    Rotameters are simple industrial flow meters that measure the flow rate of liquid or gas in a closed tube. The flow rate inside the rotameter is measured using a float that is lifted by the fluid flow based on the buoyancy and velocity of the fluid opposing gravity pulling the float down.

    Level Indicator Transmitter

  • Level Sensor
    Level sensor is a device that is designed to monitor, maintain, and measure liquid (and sometimes solid) levels. Once the liquid level is detected, the sensor converts the perceived data into an electric signal. Point level sensors are designed to indicate whether a liquid has reached a specific
