1. Upstream and downstream differentiation of ultrasonic flowmeter preamplifier

Ultrasonic flowmeter calculates flow rate by measuring the time difference between the propagation of sound waves in the forward and backward directions, and its upstream and downstream differentiation is crucial for measurement accuracy. 1. The core differentiation standard for ultrasonic flow meters is mainly based on the relative relationship between the sound wave propagation path and the fluid direction: • Upstream sensor: installed in the direction of the fluid source, where the sound wave is first emitted • Downstream sensor: installed in the direction of the fluid direction, receiving the sound wave signal emitted upstream. 2 Specific differentiation method 2.1 Physical installation location identification - View sensor housing identification: Most products will indicate "UPTREAM" (upstream) or "DOWNTREAM" (downstream) - Cable connection identification: Upstream sensors are usually connected to interfaces marked with "UP" or "In" on the host. 2.2 Sound wave propagation time verification: Installation correctness can be verified by measuring the propagation time in two directions: - Forward propagation time: upstream → downstream

2. Application and characteristics of ultrasonic open channel flowmeter

Ultrasonic open channel flowmeter is mainly used for flow measurement of square culverts in open channels. It is widely used in water conservancy irrigation areas, sewage treatment, industrial and mining enterprise wastewater discharge, water conservancy engineering, agricultural irrigation and other fields. It has the characteristics of accurate measurement, adaptability to complex working conditions, diverse communication methods, flexible power supply, and convenient operation.

. The specific introduction is as follows: Application scenarios in water conservancy irrigation areas: It is widely used in water conservancy irrigation areas, and can accurately measure the real-time water flow of culverts, providing accurate data support for water use scheduling, water resource management, and other aspects of irrigation areas. Sewage treatment: Suitable for measuring the flow of sewage into and out of sewage treatment channels, it can help relevant personnel accurately grasp the inflow and discharge of s
