Product Overview
The US0078-000 is a 2 MHz Ultrasonic Liquid Flow Transducer designed for liquid flow measurement. It offers superior electrical performance stability and strong pressure resistance compared to similar market products. Key benefits include high sensitivity, rapid peak signal attainment for easier signal processing, and zero flow drift at varying temperatures, contributing to improved measurement accuracy in ultrasonic water meters. This transducer serves as a core element in ultrasonic flow meters, utilizing the transit time principle to calculate flow rate by measuring the difference in ultrasonic signal travel times with and against the flow stream.

Precautions
- This product is intended for use in liquid medium only, not for air medium.
- Anti-interference function in the drive circuit is recommended.
- Secondary product designs should include anti-failure functions.
- If an external case is added, use a soft rubber ring to separate it from the sensor. The front surface of the sensor should be kept free to avoid performance changes.
- Do not use the product under conditions of strong shock or vibration, in the presence of dissolved organic matter, or with applied input voltage exceeding the maximum specification.
