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 (***0)mA analog signal, HART, RS***5,
Ethernet, transfers the measurements to the control center,
meanwhile can through the wi-fi,Bluetooth,HART,RS***5, 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
SystemOvercoming 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, Whats 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, for workers dont
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.
