Model Number: 440
Key Specifications/Special Features:
Advantages:External level measurement with safetyGlobal first two-wire systemEasily installation, trial run and maintenanceAuto-diagnosed and collationVideo display and remote on spotSonar technologyWork principle:
Performance index:
- External liquid lever indicator with sonar ranging principle, using thespecial probe gets the sonar signal, probe has been pasted in the outerwall of the tank
- Main system is special sonar wave processingtechnology, using the SK Method to calculate the level value and outputof remote signal. Instrument can through the (4-20) mA analog signal, HART, RS-485, Ethernet, transfers the measurements to 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 theprobe to launch out, after liquid level reflected, the probe detects echosignal
- Echo signal by proprietary algorithm to calculate the time (t), system can calculate the liquid level value according to the formula
- Measuring range:(0.2-3)m, (0.3-5)m, (0.4-10)m,(0.5-15)m, (0.6-20)m, (0.7-30)m, (0.8-50)m
