Mechanical Flow Meter for Liquid

CX-DRFM-UE-F Double Rotator Flow Meter
 
Summarize
UE-F double rotator flowmeter (hereinafter shortened as flow meter) is a unique design, precision processing and
accurately assembled displacement flowmeter. The rotor is a spiral cavity in the sole measurement of the campaign, it can
play a role for segmentation, measurement, carry, drainage the tested liquid. The model flow meter increase in the structure
of the positioning gear, the two rotor in rotation at each other to achieve mutual contacts. The smooth functioning of
flowmeters work, low noise, wear less, accurate and high viscosity adaptable, able to measured the tiny particles in the
liquid through, thus difficult to card meters. After the flowmeter chemical nickel processing, with anti-corrosion, anti-wear
characteristics, it can work with very high performance and keep long time accuracy and stability.
Features:
1. Applies to low viscosity oil, light oil, heavy oil, crude oil with sand and water, liquid from low viscosity to high
viscosity.
2. Max. flow is 2 times larger than normal flowmeter.
3. Long life, high accuracy and reliability.
4. Minimal pressure loss.
5. 1000 meters of cable for long distance output. pulse output N=0.1L(a pulse for 1N), for direct connection with
computer networking.
6. 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.
