Oval gear flow meter RIZUR-DOM

   Oval gear flow meters RIZUR-DOM are used primarily for the control of the viscous medium. Positive-displacement flow meters are a device for efficient and exact measurement of the flow of liquids with high viscosity (up to 1 mln cP).

   With this technology there's no need for the flow control or the straight parts of the pipeline rule (which is compulsory for the operation of the majority of other flow meters). As a result, RIZUR-DOM is a compact and efficient solution on flow meter of almost any clean media.

   Temperature drops in some types of media, e.g. oils, can cause the change in viscosity. In such cases, volumetric measurement principle along with the Coriolis one provide most accurate results for flow measurement.

   RIZUR-DOM is designed for the measurement of volume flow rate of clean liquids that are under pressure (up to 400 bars) or are moving under their own weight, regardless of their viscosity and conductivity - petroleum, diesel, kerosene, animal and vegetable oils, natural or synthetic oils, chemicals, additives, paints, glue, emulsions, solvents, etc.
Flow meters RIZUR-DOM are used in petrochemical, chemical, pharmaceutical, food and fuel and energy branches of the industry.

Oval gear flow meters RIZUR-DOM are positive-displacement flow meters. They have two oval gears inside. The spaces between the gears and the frame are called chambers. The oval gears start moving under the influence of the liquid flow, driving the liquid through the flow meter with each turn.
Each full turn (360°) of the oval gear is equal to some amount of liquid. When the flow changes, so does the number of turns.
Since the amount of liquid passing through the flow meter is always the same, regardless of the flow speed, then the total discharge can be calculated by simply counting the number of gear turns. For that purpose, there're magnets on the gears themselves that produces a series of high-resolution impulses. The flow meter can be supplied with an impulse output, as well as with a secondary transducer (compact or separable design version), with an analogue output 4-20mA,HART or others. On request, flow meter can be supplied with a mechanical or electronic adder.
