Model Number: 439
Key Specifications/Special Features:
Advantages:External level measurement with safetyOn point measuring and multi point measuringEasily installation, trial run and maintenanceVideo display and remote on the spotSonar technology
Work principle:
Sonar pulse of the external liquid level switch can pass through thetank wall, pulse propagate in tank wall and liquid, then bereflected
After detect and calculate about the reflective, it can showwhether there is the liquid or not
Can send the signal to otherequipment to detect or control the liquid level
Performance index:
