Variable Area Vane Style Meters

Erdco flowmeters are variable area flow meters. The internal volume of the housing enlarges from the inlet to the outlet. The primary element is a tempered alloy vane with on e end fixed to the apex of the meter housing. As the flow rate changes, the vane is flexed in direct proportion.

Insertion Turbine Meter

The Turbo-Flo probes offer the precision of turbine technology with rugged construction. The practical design of the probe incorporates a bluff bar which protects the turbine from foreign materials in the stream as well from over insertion. Installation is simple and does not require special fittings. The Turbo-Flo probe may be installed in standard pipe tees, through pipe saddles, welded spuds and 1-1/2 full port ball valves.

Thermal Mass Meter

The Fox Thermal flowmeters are equipped with the revolutionary POWER PRO thermal mass flow sensor. The POWER PRO sensor was designed to operate at a higher power level than previous models. The elevated power level significantly increases its sensitivity to flow which results in improved  accuracy, repeatability and response time.

The Fox Thermal Mass flowmeter is the instrument of choice for reliable and accurate gas flow measurement. The instrument measures in standard units without the need for temperature and pressure compensation.

Torflow Pitot Tube

The Torflow is a multiport, self averaging flow meter with a design based on a classical pitot tube concept of fluid flow measurement.

Since its design and launch in 1985, thousands of TORFLOW flowmeters have been installed into a wide variety of industries world-wide

Ultrasonic Flowmeters

The Katronics flow meters are ideally suited to dirty or clean liquids. The measurement of flow is based on the principle the sound waves are influenced by a flowing medium. Measurements are made by penetrating the pipe wall with ultrasound and subsequent time differences, frequency variations and phase shifts of the ultrasonic signals are evaluated. The measuring technique has no effect on the flowing liquid. There is no pressure loss in the pipe and no wear on components of the measuring device.

The ultrasonic sensors are clamped onto the outside of the pipe, thus eliminating the need to interrupt the process.

Magnetic Flowmeters

The RPmag62 flow meter is suitable for use in many industries including chemical, power generation and distribution, mining, water treatment, pulp and paper, pharmaceutical, food and environmental protection. There are no moving parts in the measuring tube and there is no pressure loss. The RPmag62 flow meter has a wide measuring range and is available with a choice of wetted materials and linings to suit a wide range of applications.

Venturi Nozzle Elements and Open Channel Flow

The venturi nozzle is a hydraulic measuring element for precise flow measurement. With an insertable short venturi it is possible to detect low quantities of flow by measuring the flow height. Measuring the height is accomplished using an ultrasonic level system which calculates the flow volume.

Flow-switches

Bestobell can provide flow switches to suit any application, from clean liquids to slurries or gases, high pressures or high temperatures.

Technologies offered include mechanical paddle, thermal mass and ultrasonic.
