Transfer Standard Flow Calibrator and Prover System

The Flow Transfer Standard (FTS) Flowmeter Calibration and Proving System offers an ideal combination of high performance and low cost.

It relies on accurate Master flowmeters which are used as standards against which other Liquid or Gas flowmeters are being tested.


The FTS concept affords a high degree of portability and is equally well suited to be used in a laboratory or in-situ as an in-line proving system.

With the miniaturized data acquisition hardware, this is truly a portable flow calibrator which can literally be carried in a suitcase.

Pictured here is a Flow Transfer Standard with a custom made cart to house the manifold and master turbine meters.

Fluid input and output is connected to fittings located on the end of the cart's right side.

The wheels allow the cart to be easily moved to varius test cells for calibration.


The user friendly data aquisition operating software ensures optimal man-machine interface and easy to use operation.

Traceability to National and International Standards Organisation (PTB, BNM, NIST) is easily maintained through the use of appropriately calibrated master meters. Master meter types that can be used are among others: Turbine, Magnetic, Vortex Shedding, Coriolis, PD, Thermal Mass, Ultrasonic, Sonic Nozzles (Critical Venturis), etc.

Calibrates or proves practically any type of flowmeter including: Turbine, Magnetic, Thermal Mass, Coriolis, PD, Ultrasonic, Vortex Sheddind, etc.

Performs real-time compensations for the effects of fluid properties using temperature and pressure inputs.

Generates comprehensive, tabular or graphic reports in volumetric or mass units.
