I. overview of products

Tracking level meter is my company independent research and development of a new technology, new products, liquid level measurement using sensors, and the measured liquid non contact measurement, is a great innovation in the history of liquid level measurement.External liquid meter outside the tank continuous liquid level measurement, of the tank opening, installation can not stop, especially suitable for the old product upgrading.Instrument is safe and reliable, high precision, long service life, installation convenient maintenance, especially suitable for the liquid level of the closed container of all toxic substances, acid, alkali, high temperature and all kinds of pure liquid for precise measurements.

Two, working principle

External liquid meter uses the sonar principle. Through the measurement of sound wave in the medium echo time and calibration of the propagation velocity, the accurate calculation of liquid level height, to overcome the effect of tank wall of the ultrasonic signal, use the advanced digital signal processing technology, can realize the non-contact, high precision of measuring tank liquid level. Liquid level meter can output 4 ~ 20mA standard signal or RS-485 or Hart interface will output to the upper computer (or two meter), and meet the system's automatic control.

Three, product features

1, non-contact measurement: no need to be measured vessel opening, measuring the most ideal way in industrial instrumentation; 2, high precision, sensitive, self calibration function, to overcome the traditional liquid level meter is used for a long time, reducing the accuracy of the problem; 3, wide range of application: used for toxic the strong, corrosion resistance, high pressure, complex conditions, and the explosive gas environment of various liquid media measurement; 4, installation can not stop, not clear, without fire, tank; 5 meter reliable work, stable performance; 6, convenient installation, simple operation, no need to use repair 7, long service life, convenient; can show at the scene level value, and through the signal line which sent to the control room.
