Abstract: the precession vortex gas meter scale in oil field measurement in the development of competitive information by excellent
flow meter, flow meter production factory to provide you with quotation.
Abstract: the basic principle of precession vortex gas meter when along the axial flow of fluid into the flow sensor is fashionable, blade force fluid into the rotary motion, then produce spiral flow in the center of the vortex sprawling body.
Vortex flow precession in the venturi tube, arrived.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is the precession vortex gas meter scale in oilfield development advantage in measuring the article details.
The basic principle of precession vortex gas meter when along the axial flow of fluid into the flow sensor is fashionable, blade force fluid into the rotary motion, then produce spiral flow in the center of the vortex sprawling body.
In the venturi tube precession vortex flow, reached the contraction section of throttling the vortex flow suddenly accelerated.
When along the axial flow of fluid into the flow sensor is fashionable, blade force fluid into the rotary motion, thus produce spiral flow in the center of the vortex sprawling body.
In the venturi tube precession vortex flow, reached the contraction section of throttling the vortex flow suddenly accelerated.
After the vortex flow into the diffuser, due to the effect of reflow forced precession type quadratic rotation.
At this point, the rotation of the vortex flow frequency is proportional to the medium flow rate, and linear.
Piezoelectric sensors to detect the weak signal charge after preamplifier amplification, filtering, plastic into frequency is proportional to the velocity of the pulse signal, zui to count to send totalizer. especially after processing.
By flow totalizer. especially temperature and pressure testing of analog channels and micro processing unit, and is equipped with a transmission signal interface, the output signals.
Flowmeter in microprocessor according to the medium temperature of detected Chad medium density and pressure, complete medium and volume flow to mass flow detection.
Flow meter in the microprocessor can be carried out in accordance with the gas equation of temperature compensation, and automatically compress factor correction.
The advantage of precession vortex gas meter (
1)
Precession vortex gas meter that can detect the medium temperature and pressure, well then compressed for automatic compensation and automatic correction factor.
It also can be directly testing the standard volume of the gas or the mass flow of saturated steam.
(
2)
Precession vortex gas meter adopts advanced microcomputer technology and high-performance integrated chip, using high and new technology such as advanced micro power consumption, low power consumption.
The flow meter as well as by the battery power supply to run for a long time, but also by external power supply mode.
(
3)
The meter adopts LCD display, clear and easy reading.
With the pulse signal output, can also according to customer's need standard analog signal output 4 ~ 20 raa.
(
4)
Adopt RS485 interface and PC connected to the Internet.
64 on a machine can take each flowmeter, and only two communication thread.
Installation cost is low, making it easy for users to centralized management.
Conclusion so from the perspective of the use of oil field, the vortex precession flowmeter performance stability, small amount of maintenance.
Use of precession vortex gas meter measured data, can and the analysis and research unit block, mouth of oil well production, achieve the target of management and construction.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
Most people who see a in operation for the first time are amazed at how well the
vortex flow meter manufacturer is managed.
