Outside Measurement Ultrasonic Liquid Level Transmitters for Chemical Industrial
Advantage The sonar technology External liquid lever indicator with sonar ranging principle, using the special probe gets the sonar signal; the probe has been pasted in the outer wall 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. Pioneering the Two-Wire System Overcoming various technical dilemma, two-wire system External liquid level indicator has been successfully developed. This realizes signal processing with ultra low power consumption, Up to the standard of construction plant, Simplify the wiring installation (at the Construction Site), Sparing massive cables and installation expense, easy to anti-explosive security. Contactless level measurement with Safety Measuring the liquid, if it is the poisonous, corrosive, pressure, flammables, explosives, volatile, easy leaking liquid and so on, it will need no valve, connection tube, joints, drilling. Workers just depend on the peripherals Sonar sensor (probe detector) checking, What’s more safely, workers will not contact the liquid and gas. Easily installation, Trial run and Maintenance No effect on production, No need clean the tank when installing, trial running and Maintaining. Especially suitable for commissioning at the dangerous situations, workers don’t need to open the lid of tank. Auto-diagnosed and collation With the function of auto-diagnosed and collation, The External liquid level indicator become a more reliable and stable operation, The precision will be higher than the backward equipments. Video display and remote on the spot External liquid lever indicator can show the liquid level on the spot, meanwhile transmit the level data to the control center.
