The standards and regulations were promulgated in 1989, which played a role in standardizing the development, production and application of vortex flowmeter in China
According to statistics in 1992, there are more than 30 enterprises developing and producing vortex flowmeter in China
Matters needing attention in the installation of vortex flowmeter 1 The flowmeter must be installed as required to avoid damage to the instrument due to improper installation and affecting the measurement accuracy
2 The flowmeter shall not be installed on the long overhead pipeline as far as possible
The sagging of the pipeline is easy to cause the seal leakage between the flowmeter and the flange If it is necessary to install, pipe support points shall be set at 2D upstream and downstream of the flowmeter, the double generator and double detection element stress vortex flowmeter shall be successfully developed, and the dry calibration technical indicators shall be provided to the customer in the installation and use manual; In the measurement system, the vortex flow sensor is installed on the vertical pipe, which sends the pulse signal corresponding to the high-pressure air flow to the intelligent flow integrator
Precautions for IC card steam flowmeter installation of Qingdao Hesheng Zhiyuan Automation System Co
, Ltd
:
When the special flange of vibration resistant vortex flowmeter is welded with the straight pipe section, the sensor cannot be used for welding
During installation, the flow direction mark of the sensor shall be consistent with the flow direction of the fluid in the pipeline
Before installing the sensor, the sealing ring must be placed in the flange groove
The position of pressure and temperature measuring points, the pressure taking point is 3 ~ 5dn downstream of the sensor, and the temperature measuring point is 5 ~ 8dn downstream
When measuring high-temperature medium with distilled water vortex street flowmeter, do not wrap around the sensor connecting rod with thermal insulation material
The direction of the * cable connecting the sensor shall be far away from the occasion of strong electromagnetic field as far as possible
It is not allowed to be laid together with the high-voltage cable, * the cable shall be shortened as far as possible and shall not be coiled to reduce the distributed inductance
The large length shall not exceed 100m
Before installing the sensor of Qingdao flowmeter, the pipeline must be cleaned
Flush out the impurities in the pipe to avoid blocking the sensor after flow
The pipeline for measuring liquid must be filled with the measured liquid to prevent the formation of bubbles
Dandong IC card steam flowmeter and mixed gas flowmeter have low price
They can display various information such as instantaneous flow, instantaneous heat, cumulative flow, cumulative heat, vortex frequency, medium pressure and temperature, density, time and date
They also have rich functions such as small flow automatic compensation, power failure flow compensation and automatic meter reading
When installing and measuring gas flow on horizontal pipelines, If the measured gas contains a small amount of liquid, the sensor shall be installed at a higher place of the pipeline and processed with a CNC lathe to ensure the accuracy of coaxiality and finish, and cooperate with special process treatment, so as to overcome the common problem of the influence of the inherent self oscillation frequency of vortex flowmeter on the signal
This is the unique technical advantage of keou company in the production of vortex flowmeter
The research and development of mass vortex flowmeter has been carried out at home and abroad
Vortex flowmeter is developing from indirect mass flowmeter to direct mass flowmeter, and the signal processing technology is developing in the direction of digitization
From the application of conventional active filter to the application of * filter, adaptive filter and digital spectrum analysis, the accuracy, anti-interference ability and measurement range of vortex flowmeter are improved
Requirements for straight pipe section of IC card steam flowmeter installation:
1
The anti vibration vortex flowmeter has certain requirements for the upstream and downstream straight pipe sections on the installation point, otherwise the measurement accuracy will be affected
2
At the upstream of the installation point of Jining flowmeter, there shall be an equal diameter straight pipe section of no less than 15d (D is the pipe diameter) at the upstream of the flowmeter and no less than 5D at the downstream
3
The upstream of the installation point of digital display vortex street flowmeter has a gradually expanding pipe, the upstream should have an equal diameter straight pipe section of no less than 18D (D is the pipe diameter), and the downstream should have an equal diameter straight pipe section of no less than 5D
4
There is 90 DEG upstream of the installation point of Weihai flowmeter; For elbow or down joint, there shall be equal diameter straight pipe section of no less than 20d at the upstream and no less than 5D at the downstream of the flowmeter
5
There is 90 DEG on the same plane upstream of the installation point for supervision and inspection of the flowmeter shell; Elbow, the upstream of the flowmeter shall have an equal diameter section of no less than 25d, and the downstream shall have an equal diameter straight pipe section of no less than 5D

According to the needs of measurement, when the pressure and temperature need to be measured near the sensor, the pressure measuring point should be 3-5d downstream of the sensor, and the temperature measuring point should be 6-8d downstream of the sensor
The flow transmitter is 4-20mA analog signal output with strong resistance
It can be directly connected to PLC or DCS to reduce the correction Fen risk of both parties
Development The production unit should also concentrate on research to solve the weak links of vortex flowmeter products and improve product performance and manufacturing quality
The publicity of products should be more objective
The * cable should be used, and the * layer should be reliably connected to the grounding screw of the amplifier or grounded in the control room
When there is oil, solvent or other corrosive gas in the high-temperature or low-temperature environment or on-site air, the * cable suitable for this special occasion shall be used
