One, overview
LE1 series capacitive target flowmeter is based on the traditional target type flowmeter, with new capacitance force developed into the development of new sensors, the microelectronics technology
Induction type flowmeter, it has both characteristics of vortex flowmeter and orifice plate, no moving parts, but also has high sensitivity, and the volumetric flowmeter is comparable to the accuracy of the,
Wide measuring range. The anti overload capacitive force transducer structure, efficient chip level is the key of the new product to realize high precision and high stability,
In addition to its unique anti-interference performance in flow measurement of impurities, can replace the conventional flow measurement, especially in high viscosity, easy to medium, dirty condensate blockage and high temperature,
It has good adaptability in low temperature conditions, corrosion and other flow measurement difficult, widely used in petroleum, chemical, metallurgy, electric power, environmental protection, pharmaceutical, food and other fields.
The suitable diameter range: Phi 10~ Phi 2000 to more;
The suitable temperature range: -196 ~ C~500 ~ C;
The application of high / low pressure: 0~42MPa;
The application of various medium: gas, liquid (including high viscosity liquid and slurry), steam;
- suitable for low velocity medium, which can measure the minimum flow rate is 0.08m/s.
Two, the principle and characteristics of
1, structure
LE1 series capacitive target flowmeter is mainly composed of a measuring tube (shell), capacitance model
Force sensor, flow resistance, flow display and output part.
2, work principle
When the medium in the measuring tube flow, because of its own energy through a flow resistance (target) and the differential pressure, and the flow resistance of a force, the size of the force
Flow rate is proportional to the square, its mathematical expression is as follows:
Type: F force - flow resistance by (kg)
Cd - object drag coefficient
A - flow resistance of the measuring tube axial projection area (mm2)
P: under the condition of medium density (kg/m3)
V - medium in the measuring tube of the average flow rate (m/s)
Flow resistance (target) to accept the force F, by rigid connection transfer (rod) to the capacitive force sensor, capacitive force sensor produces a voltage signal output:
V - voltage capacitive force sensor output (mV), K - F - proportional constant flow resistance (target) by force (kg)
Thus, the voltage signal by pre amplification, AD conversion and computer processing, you can get the instantaneous flow and cumulative amount accordingly.
