Type： CX-DRFM-UE-F double rotator flow meter

Illustrate： CX-DRFM-UE-F double rotator flow meter applies to low viscosity oil, light oil, heavy oil, crude oil with sand and water, liquid from low viscosity to high viscosity.

CX-DRFM-UE-F Double Rotator Flow Meter

Brief Introduction
1.Unique design, precision processing and accurately assembled displacement flowmeter.
2.Playing a role for segmentation, measurement, carry, drainage the tested liquid
3.Increase the structure of the positioning gear and the two rotor in rotation at each other to achieve mutual contacts.
4.Working smoothly, low noise, wear less, accuracy and high viscosity adaptable, able to measure the tiny particles in the liquid , thus difficult to card meters.
5.After the flowmeter chemical nickel processing, with anti-corrosion, anti-wear characteristics,
6.Working with very high performance and keep long time accuracy and stability.

Main Features
1. Max. flow is 2 times larger than normal flowmeter.
2. Long life, high accuracy and reliability.
3. Minimal pressure loss.
4.1000 meters of cable for long distance output. pulse output N=0.1L(a pulse for 1N), for direct connection with computer networking.
5.An explosion of the Ia II CT6(intrinsic safety type); flameproof d II BT6(flameproof); protection IP56.

Working principle
As shown below, the flowmeter through a special helical rotor rotary, direct measurement of liquid flow volume.
Flowmeter on the flow of fluids in the body cavity to complete the measurement. Rotor in a spiral of liquid under the
pressure of rotation, rotor and measurement within cavity formation of the closed space(shadow) rotating once
every eight times from the shadow of the volume. So the basis of the relationship, as long as the measures the
number of rotor rotary, you can calculate the cumulative traffic volume, according to the number per second,
you can measure the instantaneous flow.
