Engaged in seamless operation, ensuring optimal performance and reliability
Working principle
Embodying the cutting-edge innovation and precision of Cold Valley Intelligent Technology (Shanghai) Co., Ltd., the Highpeak High Reliability Flowmeter operates on an ingenious principle. As fluid journeys through the vortex generator within the flow field, moving at a specific velocity, it conjures a mesmerizing dance of alternating, aligned vortex rows, known as the 'vortex street.' This fascinating phenomenon commences first on one side of the column and gracefully transitions to the other. This groundbreaking vortex-generating concept was originally introduced by the visionary Karmen, who christened it the 'Karman Vortex.' Furthermore, Karmen elucidated the intricate relationship between the frequency and velocity of this phenomenon, encapsulating it with the Strouhal number as a defining coefficient. This elegant theory forms the backbone of our flowmeter's exceptional performance, ensuring remarkable abrasion and dirt resistance.
Product Characteristics
1. Wide application, capable of measuring flow of vapor, gas and liquid;
2. Measurement results are independent of physical parameters including flow distribution, fluid pressure, temperature, density, viscosity, etc.
3. No movable parts, high reliability, long-term stable operation;
4. Abrasion and dirt resistance, unnecessary mechanical maintenance, long service life, safe and explosion-proof, suitable for harsh environment;
5. The measuring probe of sensor is packed with a special technique and boasts temperature resistance of up to 350ºC;
6. Sensor is designed by means of compensation, so as to promote meter's shock resistance;
7. The on-site displaying flowmeter with micro-power high technology and battery supply can operate with electricity for more than 5 years;
8. Electric-isolated current input, fine capability of suppressing common mode interference;
9. Good anti-vibration property, non-drift at zero point, effectively eliminate external vibration influences;
10. Surface mount processed circuit, compact structure, high reliability, wide measuring range; range ratio can be 10:1, 15:1, 20:1 and 30:1.
11. Small pressure loss, wide dynamic measuring range, low operating cost, body of stainless steel, strong corrosion resistance;
12. Pulse input, 4~20mA input or HART communication/Modbus protocol communication can connect with industrial automation system;
13. On-site LCD display, simultaneous display of instantaneous flow and cumulative total flow;
14. Calculation of density, temperature and pressure compensation, on-line inspection of compensation calculating formula, in-place button layout, convenient for parameter adjustment without any handheld communication device.
