The industrial standard KE- FLS 3000 Series is a rugged design stainless steel sensor with insertion paddlewheel technology suitable for operation at extreme pressures and temperatures. The Tungsten Carbide shaft and carbon fiber reinforced PTFE bearing provides excellent wear resistance for extended service. These are used for continuous monitoring of HVAC systems, boiler feed water, chemical productions, pure water production, RO plants, filtration systems, liquid delivery systems, cooling systems but not used for gas applications. The FLS 3000 series is offered in SS316 material for a wide range of pipe sizes and pipe insertion configurations.
1- High accuracy with fast response and good repeatability of 0.5% of max. range.
2- Wide dynamic liquid velocity range (0.5 to 6 m/s).
3- Self-Powered with ± 1% linearity in measurement value of max. range.
4- Can be used for pressure up to 103 bar as well with temperature up to 149 °C.
5- Sensors can be installed in Pipes from DN15 (1/2 in) up to DN300 (12 in.).
6- Easy to replace Rotor if damaged.
|Safety Pressure||Rotor Pin Material||Body
|FLS3001||0.5 in. - 1 in. DN15 - DN25||103 Bar||SS316||SS316||17-4PH-1SS||Klinger C-4401||7.6 Mtr.|
|FLS3002||1.25 in. - 12 in. DN30 - DN300||103 Bar||SS316||SS316||17-4PH-1SS||Klinger C-4401||7.6 Mtr.|
1- Depressurize and vent piping and system prior to installation or removal of sensor.
2- Don’t exceed maximum temperature or pressure specs as mentioned.
3- Do not use this product for any purpose other than liquids for which it is designed.
4- Drill a 27 mm (1-1/16 in.) diameter hole through the one surface of the pipe and thoroughly deburr the inner and outer edges of hole.
5- Tack weld the Mini-Tap fitting onto the pipe making sure the hole in the pipe is lined up with the Mini-Tap fitting hole and weld the Mini-Tap fitting onto the pipe.
Caution: Welds must be made by a certified welder who is licensed to weld stainless steel and other high carbon grade steels.
6- Set the gasket supplied with the fitting onto the fitting flange, making sure the holes align. Remove the red rotor protection cap and insert the sensor into the fitting, making sure not to bump the rotor assembly. Make sure the arrow on the side of the sensor is pointing in the direction of flow .Slip two washers onto each bolt and insert the bolt/washer onto each of the four fitting flange holes.
7- Snug all four flange bolts in a crisscross pattern. Using a torque wrench and torque the flange nuts in a crisscross pattern to 52 foot pounds.
|Sensor Code||Pipe Diameter Size Range||Length (L)|
|FLS3001||0.5 in. - 1 in. DN15 - DN25||1.5 in. 38.4 mm.|
|FLS3002||5 in. – 8 in. DN125 – DN200||2.5 in. 63.5 mm.|
