Flow Sensors

Our clients can avail from us, a ruggedly constructed range of paddle wheel flow sensors that is highly repeatable and delivers reliable performance. These paddle wheel flow sensors are powered from the meter that is driven by a sinusoidal frequency for output signal. Suitable for low pressure systems, these sensors measure the liquid flow rates in full pipes and are chemically compatible to many liquid process solutions. Set at proper insertion depth into the process flow, these sensors are reckoned for the following distinguishing features:

• Simple to install in up to DN900 (36 inch) pipes using custom fittings like tees, saddles and weldons
• Little or no maintenance required
• Dynamic flow range of 0.5 to 5m/s
• Easy to adopt aggressive & slightly contaminated media

The technical specifications of this range are mentioned below:

• Flow-rate range: 0.5m/sec to 5m /sec.
• Accuracy: +/-1% of full scale deflection
• Input voltage: 3.4 to 24 VDC
• Output voltage square wave (sinking): 30-35 Hz / meter / sec
• Cable length: 3 meters

Our clients can avail from us, a special range of mini sensors that is suitable for small quantity dosing and batching. Housed in robust and compact body, these inline paddle wheel sensors generate a frequency & signal proportional to the flow. Mounted horizontally, these paddle wheel mini sensors are widely used in industries like pharmaceutical and beverages like tea / coffee dispensers, milk, cold drink, or beer dispensers. These mini sensors have a selection option for MOC that facilitates easy adoption of aggressive and slightly contaminated media. It should be noted that solid content should not exceed 1% of the volume in proportion.

The technical specifications of this range are as follows:

• Flow-rate range: 0.03L/sec to0.2 L/sec.

• Accuracy: +/- 2% of full scale deflection

• Input voltage: 3.4 to 24 VDC

• Output voltage: Square wave (Sinking) 30-35 Hz / meter / sec

• Cable length: 3 meters

• Protection rating: IP-67

• Operating temp: up to 70°C.

Our clients can avail from us, a special range of Electro Magnetic Sensors - 'poly MAG'. Housed in robust and compact body, these sensors generate a frequency & signal proportional to the flow.

Oval Gear (Positive Displacement) Sensors

We hold expertise in designing and exporting a wide range of oval gear (positive displacement) sensors that is used for accurate and repeatable measurements with normal as well as highly viscous liquids. These sensors are volumetric flow-meter with oval gears that can be used for controlling the delivered fluid. Compact in design and easy to use, these sensors operate in the following manner:

• Two oval gearwheels located inside the measuring body rotate in opposite directions when pushed by the flow

• Every gear contains two magnets and an external sensor (reed type or hall-effect sensor) that transmit a pulsing signal

• The frequency of the impulses determines the instantaneous flow rate, as every cycle corresponds to a given flow volume

Below mentioned are the technical specifications of these sensors:

• Meter body material: Aluminum / 316 stainless steel / bronze

• Rotor material: PPS/316 Stainless Steel

• Shafts: 316Stainless Steel

• O' ring: NBR (Nitrile)

• Flow rate ranges: (Liters per minute/US gallons per minute)

• Above 5 CPs: 10 to 250/2.6 to 66

• Below 5 CPs: 235/4 to 62

• Accuracy- within (of reading): +/-1% / Analogue Register +/- 0.5%

• Repeatability: 0.03%

• Maximum operating temperature: 80°C / 176°F, High temp option 120°C / 248°F

• Recommended mesh strainer size: 60 Mesh.
