Oval Gear Meter

The measurement element of this positive displacement oval gear meters consists of two precision oval gears. The revolution can be sensed by a magnetic-field-controlled pulse generator, resulting in only two moving parts i.e “oval-wheels”. These oval gear meters can be used for application of nearly all operating condition.

  • Very high / very low temperatures
  • Low and extreme high viscosities
  • Nominal Diameter DN 4 to DN 400
  • Operation pressures upto 100 bar

Conditionally suitable at low upstream pressures

Turbine Flow Meter

Turbine meters are indirect volumetric meters. The revolutions of the turbine wheel in these turbine flow meters are proportional to the volume passing through the meter. Turbine flow meters are suitable for measurement of-

  • Low viscosity liquids (e.g. L.P.G)
  • Mineral oil products
  • Crude oil with high viscosity

Nominal diameter: DN 10 to DN 600 
Measuring range : up to 10,000 m3/h
Temperature : 196- 250o C 
Pressure : up to 100 bar

Vortex Meter
Vortex Meter
Vortex meters are using the physical phenomenon of “vortex shedding”, the number of vortices generated is proportional to the flow. These vortex flow meters relatively insensitive to pipe vibrations, pulsation, temperature shocks. 

Vortex meters also suitable for steam flow rate measurements
Nominal diameter : DN 15 to DN 300
Measuring range : up to 20,000 m3/h (Gas/ Steam) 2500m3/hr for liquids.
Temperature : 200 to 4500 C
Pressure : up to 40 bar

Density Meter

The fluid to be measured passes through the oscillating element. Excited electro-magnetically, it will oscillate with its natural frequency. The frequency will be picked up by the transmitter and converted into a signal proportional to density or concentration.

Cone Meter

Measuring principle is by the rate of flow measurement by the differential pressure method. It is basically calculated by the use of Bernoulli equation. The differential pressure is a measure of flow rate.

Nominal diameter: DN 15 to DN 1400
Pressure : up to 100 bar and above

Clamp On Ultrasonic Meter

The transit time flow meter measures flow rate by calculating the spreading time of an ultrasonic wave in a liquid going upstream and downstream of a pipe. For ultrasonic flow meter it is not necessary to stop the flow to install them.
