3、 Other instructions

Good directionality. The hydrophone has no directionality horizontally and no directionality within a range of 240 ° in the vertical plane.

High sensitivity and flat response.

It has good temperature, pressure, and time stability, high reliability, and is suitable for acoustic calibration.

Suitable for long-distance signal transmission. The preamplifier converts the high impedance of piezoelectric elements into low impedance, greatly reducing coupling losses caused by long cables and minimizing geomagnetic interference during transmission.

The sound pressure sensitivity can be adjusted as needed. By adjusting the gain of the preamplifier, the sensitivity of the hydrophone sound pressure can be changed to meet the needs of actual measurement.

Underwater listening deviceUsed for monitoring leakage in water supply engineering pipelines (pipe networks), monitoring pipeline bursts, leaks, and pressure transients (water hammer monitoring). The principle for setting the distance between sensor installation positions is 800-1200 meters, and the position should be adjusted appropriately within this distance range based on site conditions.

Based on the collected acoustic data inside the original water pipe, determine whether there is a leak and identify the area of the leak.
