Intelligent rs485 4~20mA wide range ultrasonic sensor
1. Principle of Operation External liquid lever sensor with sonar ranging principle, using the temperature integrate sensor to process the sonar signal. the sensor is pasted in the outerwall of the tank. Using the patented algorithm to calculate the height of the liquid in the tank and output to a remote control system(eg.DCS) through (4-20)mA,HART, RS-485, Modbus. According the figure right, the time is taken for the signal to
be transmitted and then received from the liquid surface. Signals from the transducer are fed into the processor and then processed by patented algorithm to calculate the height of the liquid according to the formula: H=αV(t-t1)/2 H: height of the liquid v: velocity of sound in the liquid t: time between transmitted and received signal t g : propagation time in the tank wall α :liquid compensation factor
2. Applications LPG tanks liquid ammonia tanks liquid chlorine tanks liquid propene tanks liquid propane tanks Fuel tanks Acids/solvents tanks Concentrated sulfuric acid(98%) tanks Nitric acid tanks Hydrofluoric acid tanks Hydrochloric acid tanks
3. Features True non-invasive sensing technology The sensor sticks to the outside of the tank bottom Suitable for most shapes and sizes of cans Output to telemetry system - various options CNEX approved for use in hazardous areas (processor and sensor) Temperature integrated sensor Low cost, reliable & accurate tank gauging Not affected by pressure Easy installation - no tank break-in Simple retroft to existing tanks No down-time during installation No moving parts – no maintenance
