Abstract: the installation environment of sewage flow meter scale and map information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
Sewage flow meter can be widely used in municipal water supplies, iron and steel, petroleum, chemical, electric power, industry, water conservancy, to take the water resources department of conductive liquid volume flow measurement, particularly suitable for channel, flow measurement and environmental treatment in small river.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is the installation of the sewage flow meter scale environment and sketch the article details.
Sewage flow meter can be widely used in municipal water supplies, iron and steel, petroleum, chemical, electric power, industry, water conservancy, to take the water resources department of conductive liquid volume flow measurement, especially suitable for the channel, small river flow measurement and processing in the environmental protection sewage metering.
The articles we're here to discuss its installation environment provide installation diagram for user reference.
Sewage electromagnetic flowmeter
installation requirements: 1)
Electromagnetic flowmeter, sewage flowmeter installation environment choice: should as far as possible away from strong electromagnetic field devices, such as a large motor, large transformer, large converter.
Installation site should not have a strong vibration, pipe fixation, environmental temperature change is (
To prevent the solid liquid two phase change)
Installation environment should be easy to install and maintain.
, selection of sewage flow meter installation location: installation location must ensure that the pipe is always filled with liquid to be tested.
Select liquid flow pulse small place, that is, stay away from pumps and valves, elbow and other local resistance.
Measurement of bipolar (
Solid, liquid and gas, liquid)
When the liquid, you should choose is not easy to cause phase separation.
Measured pipe diameter or circumference is easy to measure, and ovality should be smaller.
, straight pipe length: sensors installed pipe straight pipe upstream side length should be greater than or equal to 10 d, downstream should not be less than 5 d (
D for the measured pipe size)
, flow control valve and regulating valve, flow control valves should be installed in the upstream side of the sensor, measured the pipe flow regulating valve should be installed in sensor downstream.
Usually, when the discharge flow control valves should be in the fully open position.
Sewage flow meter installed instance figure and requirements: 1, shall be installed in the lower part of the horizontal and vertical place, prevent the very top of the pipe installation and vertical to the touchpad;
2, should be installed in the pipeline rise;
3, in open discharge pipe installation, the lower part of the should be installed in the pipeline;
4, if the pipe head more than 5 m, on the downstream side of the sensor installation exhaust valve;
5, control valve should be installed on the downstream side of the sensor and the cut-off valve, and should not be installed on the sensor upstream;
6, sensors, import and export, cannot be installed in the pump should be installed in the pump outlet;
7, well in measuring liquid flow meter installed in the way;
Figure 7 note: 1.
3 the overflow pipe.
The entrance gate 4.
Cleaning hole 5.
7 short tube.
8 for export.
Discharge valve: how to correctly choose to install node installed correctly choose point and the correct flow meter is a very important link, if the installation link error, light person affect measuring accuracy, the person that weigh can affect the service life of the flowmeter, and even damage the meter.
Special attention should be paid to when select installation location: not the axis of the measuring electrode must be similar to the horizontal direction;
Measurement of the pipe must be completely filled with liquid.
At least 5 & times ahead;
D for flow meter diameter)
The length of the straight pipe, the rear at least three & times;
D for flow meter diameter)
The length of the straight pipe;
The direction of fluid flow and the direction of arrow flowmeter;
The pipe must have the lining can be damaged by vacuum flowmeter, special attention should be paid;
Near the flow meter should be without strong electromagnetic field;
Shall have plenty of space in the vicinity to installation and maintenance;
If the measure vibration in pipe flow meter should be fixed on both sides of bearing when measuring the mixed liquid of different medium hybrid point and the distance between the flow meter at least 30 & times;
D flow meter diameter)
The length of the cleaning and maintenance for the convenience of flowmeter in future, should install bypass pipe;
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
