What are the performance characteristics of liquid turbine flow meters?
Liquid turbine flowmeter is a precision flow measurement instrument that can be used to measure the flow rate and total amount of liquid when paired with corresponding flow integrator instruments. This turbine flowmeter is widely used in the measurement and control systems of petroleum, chemical, metallurgical, scientific research and other fields. Turbine flow meters equipped with sanitary fittings can be applied in the pharmaceutical industry.
The instrument coefficient can be set online through buttons and displayed on the LCD screen, which is intuitive, clear, and highly reliable. This product adopts *'s ultra-low power single-chip microcomputer technology, with strong overall functionality, low power consumption, and * performance. Intelligent flow display with non-linear accuracy compensation function. The accuracy of the correction formula is better than ± 0.02%.
The performance characteristics of liquid turbine flowmeter include:
1. High precision, generally up to ± 1% R, ± 0, 5% R, high-precision type up to ± 0, 2% R;
2. Good repeatability, short-term repeatability can reach 0.05% to 0.2%. It is precisely because of its good repeatability that high accuracy can be obtained through regular calibration or online calibration, and it is a commonly used flowmeter in trade settlement;
3. Output pulse frequency signal, suitable for total measurement and computer connection, no zero drift, strong resistance;
4. High frequency signals (3-4 kHz) can be obtained, with strong signal resolution;
5. Range measurement, with a medium to large caliber of up to 1:20 and a small caliber of 1:10;
6. Compact and lightweight structure, easy installation and maintenance, and high circulation capacity;
7. Suitable for high voltage measurement, there is no need to open holes on the instrument body, making it easy to make high voltage instruments;
8. There are various types of sensors, which can be designed according to the special needs of users, such as low-temperature, bidirectional, downhole, mixed sand, etc;
9. Can be made into an insertion type, suitable for measuring large diameters, with low pressure loss, low price, can be removed without interruption, and easy installation and maintenance.
The liquid turbine flowmeter has high resistance to electromagnetic interference and vibration, reliable performance, and long working life; It uses EEPROM for power down protection of accumulated flow and instrument coefficient. The protection period is greater than 10 years.
