PRODUCT DETAILS

Two Wire Non-Intrusive Ultrasonic Level Gauge

 1.     Advantage

A: No need contact the liquid, no need drilling the tank, Safe for any harmful liquid and suitable for any sealed tank.

B: Global First Non-intrusive Gauge with Two-Wire System, can save the wire cost.

C: Easy installation without flanges, save the installation cost.

D: Easy Trial run and Maintenance no need stop the work.

E: Auto-diagnosed and collation.

F: Video display and remote on the measuring value.

 

2.     Work Principle

Non-Intrusive Ultrasonic Level Gauge with sonar ranging principle, using the special probe gets the sonar signal; the probe has been pasted in the bottom of the tank. Main system is special sonar wave processing technology, using the SK Method to calculate the level value and output of remote signal. Instrument can through the (4-20)mA analog signal, HART, RS-485, Ethernet, transfers the measurements to the control center, meanwhile can through the wi-fi,Bluetooth,HART,RS-485, infrared, Ethernet debug the controller online.

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.

4 Application liquid Material


4.1 Liquid Purity:

Liquid without much sediment, crystal, auto polymer, suspended solids, some bubbles. A little is ok.

4.2 Liquid viscosity:

Dynamic viscosity of liquid medium<30mPa.s

Note: The viscosity always reducing with the temperature’s upping, so please take about the liquid temperature.

4.3Tank:

Tank material:need to use the hard steel, the material has to transfer the signal well. Such as carbon steel, stainless steel, glass fiber reinforced plastics, epoxy resins, ceramic, 16MnR, 304,316, FRP, hard rubber. The tank wall’s inside and outside should even. If the tank wall has more layers materials, the space between layers should be touching closely, without babbles and air. For Examples:Sulfide hard rubber lining, the lining of epoxy resin, stainless steel lining, titanium lining.
