Digital Flow Meter

Our Turbine Flow Meter has a flow sensor with a magnetic muti-bladed spinning rotor (impeller) mounted inside at right angles to the flow. The rotational speed of the impeller is proportional to the velocity of the fluid. The pulse generated is transmitted and converted into a volumetric measurement.



  • Digital Flow Meter Measuring Flow Rate from 0.05 m³/hr to 500 m³/hr

  • Combined indicator / Totalizer / Batcher / Rate switch / Pulsar Mode

  • Dual Sensor, Dual Line, Single Meter, for RO Applications

  • Remote or Local Reset

  • Optional Computer Interface with RS485 or 4-20mA Output

  • Batcher And Totalizer

    Relay gets energized after a fixed quantity of water passes through the sensor. The batcher has a auto reset, manual reset & dual relay operation facility. Batch quantity counts downwards till zero value.

  • Flow Compariator

    The meter is supplied with two sensors for RO permeate and reject line. The meter displays both the flow rates and calculates percentage recovery.

  • Rate Switch Mode

    The relay is programmed to get energized whenever actual flow falls below the set value. Display shows “LOW FLOW RATE”. Ideal for flow interlock, chemical dosing.

  • Pulser

    Meter can be configured to any metering /dosing pump. Chemical dosing can be done on-line proportional to flow.

  • Optional Data Logger

    The flow meter is available with data logger option where flow rate & total flow with date and time is stored in a 2GB Memory card.

Flow Sensor

Various types of sensors available from 10NB to 300NB line size with wide range of process connection as well as material of construction

• 6NB , 20NB , 25NB & 50NB Full bore

• 40NB to 300NB Insertion type

Flow Sensors

1. Full Bore Sensor


•  Inexpensive and accurate

•  All Plastic wetted parts

•  Easy to install and maintain

•  Threaded housing allows field maintenance.

•  Each fitting individually calibrated and marked with K factor. (ml/pulse)

•  Ceramic ball bearing for superior low flow performance

•  High amplitude pulse output signal can travel even 100 meter distance without the need of transmitter

•  Sensor can be used directly with PLC or Data logger

•  For best results it is recommended to provide a straight run of 10 and 5D on the upstream and downstream respectively
