Summary

Non-Intrusive Ultrasonic Level Gauge adopts the principle of ultrasonic echo ranging, uses the special probe externally attached to the container to collect ultrasonic signals, and uses the special algorithm to accurately calculate the liquid level position in the container.
The calculated liquid level value is displayed locally and the remote signal is output. The instrument can output the result to the control center through (4 ~ 20) mA analog signal, Hart, RS-485 and other interfaces, and can also be debugged online through Hart, RS-485 / Modbus, infrared and other interfaces.
Like the picture, Measure the liquid level, the sonar wave signal from the probe to launch out, after liquid level reflected, the probe detects echo signal. Echo signal by proprietary algorithm to calculate the time (t), system can calculate the liquid level value according to the formula.
Non-Intrusive Ultrasonic Level Gauge is currently used in LPG tank, liquid ammonia, 98%sulfuric acid, etc

Two Wire Non-Intrusive Ultrasonic Level Gauge

The Non-Intrusive Ultrasonic Level Gauge is in use everywhere where the level of liquids in tanks has to be measured continuously and contactlessly. Application possibilities for radar gauges can be found in almost all areas of industry. Sewage treatment plants and water purification plants in particular, but also other environmental engineering facilities as well as power generating stations now rely on cost-effective radar sensors for continuous level measurement.

Measured substance

In general, the dynamic viscosity of the measured medium is required to be less than 10 MPa. S. When 10 MPa. S < dynamic viscosity < 30 MPa. S, the measure range may be reduced and the blind area may be increased. It cannot be measured when the dynamic viscosity is > 30 MPa. S. (1 MPa. S = 1 CP). There should be no dense bubbles in the liquid; there should not be a large number of suspended substances in the liquid, such as crystals; there should not be a large number of sedimentary substances in the liquid, such as mud and sand. The temperature of the measured medium shall be within – 50 ℃ ~ 100 ℃.
