Metal Variable Area Type Flow Meter are designed to measure flow rate of liquids and gases under critical conditions. It consists of a tapered metal tube, an indicating assembly and float. A magnet encapsulated in float couples with rotating magnets are connected to an indicating pointer. Henceforth, the movement of the float is accurately indicated in terms of flowrate.
They are intended for application where high pressure, temperature or corrosive conditions preclude the use of conventional glass tube. These are all Metal Variable Area Type Flow meter design to measure flow rate of Liquids & Gases under critical conditions. It consists of a tapered metal tube, an indicating assembly and a float. A magnet encapsulates in float couples with rotating magnets connected to an indicating pointer, thus the movement of the float, is accurately indicated in terms of flow rate.

When fluid or gas flows through a taper tube containing a float, a pressure difference of P1 and P2 is created between upper and lower side of the float. The float moves upwards by a force obtained by multiplying the pressure differential by the maximum cross-sectional area of the float.

Based on Bemoulli's theorem, the principle mentioned above can be theoretically expressed as follows. Due to taper tube, as the float moves upwards, the fluid passing area increases as a result of which the differential pressure decreases. Upward movement of float stops when the dead load is dynamically balanced by the differential pressure. Tapering of metering tube is so designed that the vertical movement of the float becomes linearly proportional to the rate of flow and the scale is provided to read the position of the float, thus giving birth to flow rate indication.

Product Description:

The Electromagnetic Flowmeter or Mag Meters are suitable for flow measurement in all kinds of conductive fluids, and it is especially suited for flow measurement of Water, Waste Water, Sludge and other fluids containing particles. The flow meter is easy to install and put to service. 

Measurement : 
Electromagnetic flow meters may have either Direct Current (DC) or Alternating Current (AC) excitation. When systems are AC excited, electrostatic and/or electromagnetic noise may influence the measurements. A DC excited system however, is less sensitive to noise produced by electromagnetic induction, simply because the voltage induced over the electrodes will be a DC voltage. The drawbacks are measurement errors due to electro-chemical polarization between the electrodes and the fluid.The Electromagnetic Flow Meters are excited by a 2.5 Hz square wave and thereby eliminate the drawbacks of both DC and AC systems. A microprocessor receives and measures the amplitude of the pulse with a 16 - bit resolution, and converts and displays the result on the display unit.

Working Principle:

  • This is working on the principal of faraday`s law which states that when a conductor moves through a magnetic field of a given strength a voltage is produced in the conductor and proportion to the relative velocity between the conductor and the magnetic field.

Flowtech Vortex Flow Meter is based on Karman vortex street Principal for detection and metering the Liquid, Gas and Steam. It is widely used in Petroleum, chemical, metallurgy, heat supply industry, etc.

Vortex Theory: One triangular prism vortex generator in the flow meter, regular vortex will be generated at both the sides of triangular prism, which is called Karman swirl. Suppose the vortex generation frequency is f, the average flow velocity of medium is V, d is the width of the surface of triangular prism incident flow, then we get the computation formula:


1. Pure liquids and hydrocarbon with low viscosity (< 10 cP)
2. Water Industry
3. Chemicals that suitable with S.S. 316 Material
4. Saturated steam
5. Superheated steam
6. Industrial gases
7. Compressor air measurement

Gas : Air, oxygen, nitrogen, coal gas, natural gas, chemical gas
Liquid : Water, high temperature water, oil, food liquid, chemical liquid, steam: saturate steam, overheated steam 

1. Integrated Pressure and Temperature Compensation
2. 4-20 mA, pulse with HART; Optional Pulse with RS 485
3. Wide temperature range upto 350 C
4. Embedded Sensor,
