Overview
Liquid Precession Flowmeter (also known as Liquid Swirlmeter) with advantages of wide flow, great shock resistance, no moving parts, long life, strong adaptability and high precision, etc. Widely used in food, pharmacy, chemical industry, oil and other industries, it is the first choice of liquid measurement in the environment with no viscosity and with strong noise.
Features
2. Use 16-bit computer chip, high integration, small size, good performance, powerful overall instrument function.
3. Use dual detection technique which can effectively improve the strength of the detection signal, and to suppress the interference caused by the vibration of the line.
4. Use domestic leading intelligent vibration resistance technology which effectively suppresses interference signals caused by the vibration and pressure fluctuations.
5. Use Chinese characters, English dot matrix display with more display digits, easy and intuitive to read.
6. Various output ways: pulse, equivalent, analog signals (two-wire 4 ~ 20mA, three-wire 4 ~ 20mA and four-wire 4 ~ 20mA), RS485, Hart protocol and so on.
7. If it is necessary, can input pressure and temperature signals to display the pressure and temperature of the liquid.
8. With high accuracy, up to 0.5%, and good repeatability.
9. Overall instrument is with low-power consumption, with inside battery power supply, or external power supply.
10. A variety of materials, measurable for special liquid, such as liquid chlorine with red copper material.
