SS ( Stainless Steel ) Paddlewheel Flow Sensors - JT-122

We are Manufacturer, Supplier, Exporter of SS ( Stainless Steel ) Paddlewheel Flow Sensors / Transmitters, SS High Pressure Flow Sensors and Our setup is situated in Pune, Maharashtra, India. City wise / country wise Channel Partnership enquiries also solicited all over the world. Few of our concepts have already awarded patents in India and many new designs are applied for the patent, recently.


Insertion SS Paddle Wheel Flow Sensor (Non-Magnetic Coupling)

JT-122 is only choice for raw water application in MS pipelines with ferrus particles / rust, Featured with Stainlesssteel Paddle and Non-magnetic Coupling between paddle and electronics, JT-122 is most robust and advance Sensor in the family of Paddle Wheel Sensor worldwide in all INDUSTRIAL APLLICATION. With proper installations, JT-122 sensor can be installed in wide range of pipe sizes.

• Use of filter before Flowmeter is necessary
• Straight Run conditions given in manual must be maintained while installation


  • Suitable for Harsh Industrial applications.
  • Open cell design for linear & repeatable output.
  • Dynamic range with virtually no pressure drop.

Straight inlet and outlet distances that must be maintained when installing fittings in pipe lines in order to achieve turbulent flow conditions. The most important layouts that could lead to turbulence in the flow are shown below, together with mentioned minimum and inlet and outlet distances. These insure turbulent, problem-Free measurement conditions at the measurement point. For more Installation guidelines please refer manual. for best results Reynolds number (R) is greater than 5000 especially for viscous liquids. to Calculate R use following formula


1. In Vertical Piping only Upstream flow is recommended.
2. Flow Meter should be installed before valve.
3. Y type strainer is must for recommend result.
