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. Is there a requirement for the insertion depth when installing the Cologne ultrasonic flowmeter?

There are clear requirements for the insertion depth of the probe when installing the Cologne ultrasonic flowmeter, and it must be strictly operated according to the specifications. 1 The determination of insertion depth is mainly determined by the diameter of the pipeline, and the larger the diameter, the deeper the insertion depth. Small pipe diameters (such as below DN100) are usually inserted by a few centimeters, while large pipe diameters (such as above DN1000) may need to be inserted by more than ten centimeters or even deeper.

2. Core installation requires that the probe must reach a stable flow velocity area near the center of the pipeline to ensure that the average fluid flow velocity is captured. Insertion too shallow or too deep can cause measurement errors and even damage to the sensor. 3. Specific operating specifications vary depending on the insertion depth of different models, and the installation manual provided by the manufacturer must be strictly fol
