Electro Magnetic Flowmeter

Electro Magnetic Flowmeters are based on Faraday’s Law of Electromagnetic Induction. When the conductive fluid flows through a magnetic field of the sensor, an electric voltage proportional to the volume flow is generated between the pair of electrodes and transmitted to the output device.

The flow and volume will be displayed at the electronic transmitter
No disturbance or restriction of flow
No moving parts – no wear and tear, virtually no pressure loss
Insensitive to fluid density, temperature, pressure, viscosity
Can be used for different types of conductive liquids (calibration with water required)

Applications: flow and energy measurement for water based liquids, (conductive liquids)

Variable Area Flowmeter

The float of a VA Flowmeter easily moves up and down in the conical measuring tube. The vertical position of the float, obtained as a function of the flow velocity of the measuring media, is an indication of the flow rate. This flow rate can be read directly on the scale of the measuring tube.

Turbine Flowmeter

Fluid entering the meter first passes through an inlet flow straightener that reduces its turbulent flow pattern. Fluid then passes through the turbine, causing the turbine to rotate at a speed proportional to fluid velocity. As each turbine blade passes through the magnetic field generated by the meter’s magnetic pickup, an AC voltage pulse is generated. These pulses provide an output frequency that is proportional to volumetric flow.

Notice: for clean water or oil based applications, a filter is necessary if the liquid is not clean (containing solid particles, etc.)

Turbine Flow Meters are also availabe for Gas Applications.

Gas Turbine Flowmeter

The operation of the International Gas Turbine Meter is based on the measurement of the velocity of gas. The flowing gas is accelerated and conditioned by the meters straightening section. The straightening vanes prepare the gas flow profile by removing. undesired swirl, turbulence and asymmetry before the gas flows to the turbine wheel. The dynamic forces of the flowing fluid cause the rotor to rotate.

The turbine wheel is mounted on the main shaft, with special high precision, low friction ball bearings. The turbine wheel has helical blades that have a known angle relative to the gas flow. The conditioned and accelerated gas drives the turbine wheel with an angular velocity that is proportional with the gas velocity.

Vortex Flowmeter

Vortex Flowmeters measure the volumetric flow of fluids (gases, vapors, liquids) in closed pipes. It is based on the Vortex shedding principle, (or Karman Vortex Effect). The fluid passing through the measuring tube is separated by a triangular prism with a broad flat front and generates two lines of eddies or vortices, the Karman Vortex shedding street. The vortex shedding frequency is proportional to the flow rate.It is detected by a sensor with 4 piezo-electric elements and converted into an electronic output signal.

BYPASS

The bypass flow meter operates on the differential-pressure method. A ring with an orifice plate is installed in the pipeline. The orifice plate causes constriction of the flow and effects a drop in pressure. This pressure drop is proportional to the square of the flow rate.

If the pressure tap upstream of the orifice plate is connected by a pipe to that downstream of the orifice plate, a partial flow will flow through that pipe. This partial flow is proportional to the flow rate in the main pipeline.

The partial flow can be turned on and off, as required, by installing two ball valves in the bypass line.

The low-cost device in PVC is frequently used in swimming-pool water technology. The device in PVDF is suitable for the flow measurement of aggressive media, e.g. in water treatment, while the stainless steel type is mainly used for flow measurement of air and gases. The measuring range extends from 0.02 – 0.16 m³/h to 300 – 1800 m³/h for H₂0, and from 0.15 m³/h – 1.5 to 1200 – 6000 m³/h for air at STP.

Positive Displacement

Positive Displacement Flowmeters are precise, reliable and rugged instruments for the volumetric flow of clean liquids including Solvents, Alcohols, Fuels, Oils, additives, chemicals, food bases, paints and viscous emulsions in general industrial, petroleum and chemical applications that require high degrees of accuracy and repeatability. They operate on the Positive Displacement principle using a gear technology (oval gear, tri gear, helical gear), or a sliding/rotary vane or bi-rotor alternative. Each rotation of a gear, (or vane) is proportional to a discrete unit of volume, in turn, the speed at which the gears rotate is directly proportional to flowrate. Output sensors (e.g. Reed and Hall Effect sensors) detect the movement of the gears, thus allowing local or remote instruments to display flow total, rate of flow or facilitate batching applications.

Flow Nozzles are an alternative to orifice plates whenever it comes to the measurement of high speed flows.Flow Nozzles are an alternative to orifice plates whenever it comes to the measurement of high speed flows.Its unique design features gives an exceptional strength, allowing a 60% higher flow rate. Compared with the venturi tube, the flow nozzle is cheaper, whereby the pressure recovery is not as high. Similar to venturi tubes, flow nozzles are maintenance free. Used for applications which do not support high pressures and therefore do not allow much pressure loss. Allows flow-measurements of gases, steam, water and condensates.

VENTURI TUBES
