Product Description

Principle of Operation

The HGUL range of compact ultrasonic level transmitters are designed to measure liquid and solids levels up to a range of 20 meters. The range can be configured by the keyboard and display. The HGUL is mounted on top of the vessel or tank. The microprocessor in the HGUL fires an electronic pulse, which the transducer converts into an acoustic pulse. The pulse travels to the level that is being measured and is reflected back to the transducer. The transducer then converts its energy back into an electronic signal and stops the counter in the microprocessor, which then knowing the
Speed of sound through the air, can accurately determine the distance.

Installation

HGUL series can be mounted easily using fixing screw, please notice:
1. The unit should be installed higher than the highest Level of liquid surface to avoid the Blanking zone, and exactly perpendicular To liquid surface.
2. When necessary insert a rubber gasket between the flange of tank and PVC 3flange in order to cut off noise source.
3. When installation, the unit should be mounted far away from wall of tank because of angle of beam.
