( Hechi CWS flowmeter source)
In the sixties used in industrial flow measurement, flow measurement is mainly used to solve high-viscosity, low Reynolds number fluid has undergone pneumatic and electric table table two stages of development. LDC ( series Hechi CWS flowmeter It is in the original strain gage Hechi CWS flowmeter Basic measurement principle based on the use of the latest capacitive force sensor as a measurement and transmit sensitive components, while the intelligent use of modern digital processing techniques and developed a new flow measurement instruments.
( Hechi CWS flowmeter product description)
Xiamen Jing Chuan LDC series Hechi CWS flowmeter , Using new capacitive force sensor with high sensitivity, accuracy, no moving parts, small pressure loss.

• wide temperature range: -196 ° C ~ 500 ° C;
• For high / low pressure working condition: 0 ~ 42MPa;
• For low flow rates medium flow rate of the lowest measurable 0.08m / s.
( Hechi CWS flowmeter Product Principle)
When the medium flows in the measuring tube, the kinetic energy of the Target by its own generating pressure, the force generated on the target plate, so that the target plate displacement trace, the size of the force proportional to the square of its velocity and media The mathematical formula:
F = Cd`A`ρ`V2 / 2
F: Target suffered force
Cd: fluid resistance coefficient
A: Target axial projection area of ​​the measuring tube
ρ: density of the medium conditions
V: medium in the measuring tube characteristic velocity
Target suffered the force transmitted through the target rod elastomer sensors produce small changes, through circuit switching, outputs a corresponding electrical signal.
Uses sensors is crucial core of the new product truly high precision and high stability, completely changed the original target flowmeter drift strain, anti-overload (shock) is poor, there is a static sealing point and various other restrictions, not only played the original target flowmeter technology, but also has a measurement accuracy of volumetric flowmeter comparable, coupled with its unique anti-jamming, anti-impurity properties, can replace conventional flow metering flow can be measured in addition to problems, especially with a good adaptability in low flow, high viscosity, easy to pour easily blocked, high temperature, highly corrosive, strong vibration and other flow measurement in difficult conditions. CWS has been widely used in metallurgy, petroleum , chemical, energy, food, environmental protection and other fields flow measurement.

( Hechi CWS flowmeter Installation and commissioning on request)
1. The high temperature (80 degrees to 500 degrees), at room temperature type (-30 degrees to 70 degrees), low temperature (-40 to -200 degrees) meter installation:
a, normal type, low temperature, high temperature type flowmeter depending on the operating conditions using horizontal, vertical or inverted mounting (with factory calibration single subject);
b, medium temperature at 300 degrees, the user response flowmeter housing insulation measures taken to prevent damage to the heat radiation header (header operating temperature of -30 to 70 degrees), the same way the operating temperature of -100 degrees below medium , but also to take freezing measures;
f, meter diameter and pipe diameter connected to try the same size, in order to reduce the flow interference, causing measurement error;
g, when the flange and clamp-on flowmeter installation, should pay attention to the inner sealing gasket between the flange hole larger than the flowmeter and process pipe diameter 6-8mm and whether coaxial, in order to avoid its interference stream affect the accuracy of measurement;
We must ensure that the fluid surface facing the target sheet strength, weld short tube height 100mm (from the pipe wall to the flange sealing surface distance) by h, the insert meter installation, the short tube and flange welded to the pipe ;( figure 2)
i, the completion of the process for the new pipeline, should first conduct an initial purge and then install the meter;
c, in order to ensure accurate measurement of the flow meter is required straight pipe before and after the set; (Figure 1)
d, in order to ensure the flow meter in the inspection and replacement without affecting the system work, should try to set the bypass valve (3) and shut-off valves (1,2); (Figure 1)
e, due process requires can be mounted vertically, the measured medium flow by the bottom, but also from top to bottom, but the supplier shall explain when ordering;
j, the outer wall of the measuring tube direction of the arrow to the measured medium flows;
k, meter housing must be grounded, if not ground conditions should explain the factory;
l, the flowmeter connecting flange specifications execute GB / T series standards, according to user requirements of special processing (in a single factory calibration date).
2, the meter is set zero (zero meter must be installed after the operation) due to capacitive force sensor and Baffles have self-respect, when the meter is not installed by horizontal orientation condition, you need to reset the meter to zero. Operational procedures for the : (can also be directly set to zero when there is no medium flowing in the pipeline, the high temperature and low temperature type flowmeter must make the pipeline operating temperature after the temperature reaches zero) a, close the valve downstream of the meter; b, slowly open the upstream of the flowmeter valves, flow meter filled medium; c, slowly open the valve downstream of the meter, so that the meter is running about 10 minutes; d, shut down the meter, the downstream valve, and to determine the pipeline flow is zero; e, zero key operation ( must operate without any magnetic tool zeroing key, otherwise zero key may not operate)
3. Precautions not permitted to directly before or after the meter measuring tube end installed valves, elbows and other parts of fluid flow pattern changed dramatically in the front and back if you need to install valves, elbows and other parts at the meter before and after the pipeline should also try to ensure that the straight sections length.
