Rotary liquid flowmeter EMIS-DIO 230 is designed to measure the flow rate of oil products, bitumen, diesel fuel, heavy oil and other liquids, for which high measurement accuracy is required. Rotary flowmeter EMIS-DIO 230

Metering technology based upon spiral rotors is applied in the rotary transducer. Such technology provides long-term performance stability and reliability. So the flowmeter can be used for measurement from water to bitumen.

The Rotary liquid flowmeter EMIS-DIO 230 is applied as:

  • liquefied gas meter;
  • counter of gasoline, kerosene and other light oil products;
  • diesel fuel meter;
  • fuel oil counter;
  • bitumen counter.

Rotary liquid flowmeter EMIS-DIO 230 is designed to control the technological accounting of commercial operations of discharge / loading, dosing and pumping as part of stationary and mobile units.


Rotary liquid flowmeter EMIS-DIO 230 is applied to measure the liquid flow rate, such as petrol, diesel, oil, fuel oil, bitumen and other liquids with different viscosity parameters. It is effective if:

Rotary flowmeter EMIS-DIO 230

  • the high measurement accuracy is desired;
  • no opportunity to provide the straight run segments;
  • the flow measurement is desired without external power supply;
  • the high pressure loss in the pipeline are not permitted it is not possible to use mass flowmeters and differential pressure transmitters;
  • it is necessary to measure very viscous fluid flow (fuel oil).

Common tasks:

  • measurement of the flow rate of crude oil on the oil-wells;
  • measurement of the flow rate of oil products on the oil refining and tank farms facilities for pumping;
  • measuring during loading/discharge of tank car and other vessels;
  • refueling of vehicles and measurement of fuel consumption;
  • dosing of liquids at oil, petrochemical, food, pharmaceutical and other industries facilities
  • as a master flowmeter in the stationary verification stands and mobile provers;
  • accounting for the flow rate of highly viscous liquids, fuel oil.

Reduce design and installation costs;

  • Built-in counter with the indicator provides to use the Rotary liquid flowmeter EMIS-DIO 230 without the auxiliary recording equipment so the total cost is reduced (assembly and installation costs).
  • Does not require straight run before and after the flowmeter installation point, which decreases pipeline preparation costs
  • The availability of widely used analogue output signals and built-in digital interface provide to use the Rotary liquid flowmeter EMIS-DIO 230 in the metering and dose systems and to control equipment performance.

Lower operation and maintenance costs

  • Wide range of viscosity allows to use the flow meter EMIS-DIO 230L for mediums with changing parameters.
  • Calibration can be executed with liquids of different viscosity, including water, which reduces calibration costs
