KRAL Volumeter® for research and production test stands. Laboratory measurement precision is achieved despite fast flow changes and fluid oscillations.
The ideal conditions at the Bureaus of Standards however show the potential of KRAL precision. The screw spindle-metering from the KRAL Volumeter is on one hand very robust and handles the oscillation from pressure waves. On the other hand, the spindles are very quick and can follow fast changes of the flow velocity. Optional pressure pulse compensation is available that detects transient fluid waves.
Please consider that we are a manufacturer of high quality displacement pumps and flowmeters for liquids. The products (pumps with magnetic couplings, high pressure flowmeters and flowmeters – chemically resistant) mentioned on this portal are only part of our product range. Please find more detailed information on our website or directly from us.

The Brooks BM Series positive displacement oval gear flow meters are designed for applications requiring high accuracy measurement of clean liquids with viscosities up to 1 million cP. All meters are available with a pulse output from a reed switch or solid-state Hall effect switch for remote registration and/or totalization. Two optional LCD displays offer rate, resetable total, non-resetable total and the option for simple batch functions.

Chemical injection fluids are normally viscous and are therefore natural applications for the VFF meter. The flowrates are relatively low and the pressure is high compared to most general industrial applications. The VFF Rotary meter is the ideal measuring element for these service requirements. Long term stability of metering and reliability is assured by the basic simplicity of design and quality of production.
VFF Meter Design & Advantages
The heart of the VFF meter is a simple but precisely made, oscillating rotor that sits freely within the rotor chamber of the meter. It is manufactured in a variety of materials. The meter principle is of 'positive displacement'. The rotor is driven 'positively' by the flow, which passes through the flowmeter in 'discrete pockets' with minimum fluid 'slippage'. This gives inherently greater accuracy than is available from axial flow turbine type meters for a low flow of a fluid more viscous than water. Each meter provides a exceptionally wide flowrange and has excellent low flow metering capability.
