We are Manufacturer, Supplier, Exporter of Plastic Paddlewheel Flow Sensors / Transmitters 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.
GENERAL DESCRIPTION
JT-121 is paddle Wheel type Polymer body Flow sensor suitable for clear liquid application. Being light weight and compact, Installation is easiest, still robust. Vats JT-121 is most simple and most economical flow sensing device for clear liquids.Proven and long lasting bearing materials has made this sensor a common choice of all OEMs. JT-121 sensor can be installed in wide range of pipe sizes. Variety of materials is available in installation fittings like ABS, PVC, and SS. These fittings include Tees, Saddles, with specific Weld Ends, Thread Ends, Flange Ends and Weldon Adaptor.
• Use of filter before Flowmeter is necessary
• Straight Run conditions given in manual must be maintain while
installation

Overall accuracy of +/-2 % the reading for 10-100 % of Flow Range & +/ 5% for 0-10 % of flow Range.
ELECTRICAL WIRING
Variety of Electronic Readers cum controllers are available.
MECHANICAL
Straight inlet and outlet distances that must be maintained when installing fittings inpipe lines in order to achieve Laminar flow conditions. The most important layouts that could lead to turbulence in the flow areshown 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
NOTE :
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.
