Flow Measurement & Control


Low volume rotating vane flowmeter

April 2019 Flow Measurement & Control

Instrotech is offering Kobold’s DTK rotating vane flowmeter for small quantities, a versatile, efficient and very economic piece of equipment. This flowmeter was specially developed for use in low viscosity liquids. Its compact construction means it can be used in machines with restricted space as well as in industrial systems. A special advantage of this gauge is its long-term stability and robust construction.

In the DTK flow gauge, the medium flows through a specially formed flow casing, causing the impeller to rotate. Two magnets on the impeller generate electrical impulses in a Hall sensor. The frequency emitted by the electronics is then directly proportionate to the flow velocity. Down-line electronics can use these signals for measuring, monitoring and dosing.

With a measuring range of 0,05 – 0,6 litres per minute to 1.0 – 12 litres per minute and a measuring accuracy of 2% from measuring range full-scale value, the measuring device can be used universally.

The maximum medium temperature is 140°C and the maximum pressure 30 bar. This means it can also be used under harsh industrial conditions. In order to cover a wide range of applications the housing, nozzles and axle have been made of high quality steel and the impeller is made of PVDF. Mechanical connection is provided by means of either a G thread or an NPT thread.

Areas of application of the DTK rotating vane flowmeter include low viscosity and non-conductive liquids, volume dosing with external electronics, laundry machines and PCB manufacture machines, and agriculture.
