HT100BX split type ultrasonic level gauge

Durable and stable sensors suitable for harsh industrial environments;
• Advanced algorithm integrating rich field experience can effectively overcome field interference such as foam and surge;
The ultrasonic transducer adopts imported piezoelectric ceramic materials and acoustic matching technology to improve emission efficiency;
The transducer is equipped with a built-in temperature sensor to achieve real-time automatic temperature compensation of the measured values;
Program controlled automatic emission energy adjustment takes into account both large range and small blind spots;
Blind spots can also be manually set to block interference signals near the probe;
4~20mA isolated current output, optional fieldbus interface.

Ultrasonic level gauge includes two parts: transmitter (secondary instrument) and sensor (sensor cable customized according to the site, instrument with 10 meters)

The installation of the transmitter should pay attention to the following points:
1. Special attention should be paid to avoiding direct sunlight, excessive vibration, direct exposure to rainwater, proximity to large motors, or exposure to strong electromagnetic fields on the transmitter.
2. The output signal line of the instrument must be dual core shielded
3. Instruments must have strict grounding.
4. Leave sufficient space for the opening and maintenance of the transmitter enclosure.
5. As much as possible, the transmitter should be installed slightly above the operator's level of sight, which will facilitate normal instrument inspection or control operations.
Ultrasonic transmitters are generally mounted by hanging, using three positioning holes behind the instrument, as shown in the following figure

Please note when installing ultrasonic sensors:
1. The emission surface of ultrasonic sensors must be horizontal;
2. The installation height of ultrasonic sensors should be less than the range of the instrument;
3. The height from the surface of the ultrasonic sensor to the highest liquid level should be greater than the blind spot of the instrument;
4. The distance from the ultrasonic sensor to the pool wall, riverbank, and embankment generally needs to be greater than 0.5 meters. If the wall is not smooth and has obvious protrusions, it is necessary to increase the distance appropriately;
5. The installation position of the sensor should avoid areas directly below where there are significant fluctuations in the liquid level, such as the inlet and outlet ports;
6. If the requirements of 4) and 5) cannot be met, it is necessary to consider installing PVC pipes with a diameter of about 100mm on site and placing the sensors of the instrument in the PVC pipes.
