Is there any 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 followed. Cologne will provide specific insertion depth values, calculation formulas, or installation positioning templates for each model. Special tools should be used for accurate positioning during installation, and signal strength and quality indicators should be used to verify whether the installation position is qualified after installation.
2. The introduction of ultrasonic flowmeter is concise and easy to understand.
The pipe section ultrasonic flowmeter is an instrument that measures the liquid flow inside a circular pipe based on the principle of "velocity difference method".
. It adopts advanced multi pulse technology, signal digital processing technology, and error correction technology, making flow meters more adaptable to the environment of industrial sites, and measuring more conveniently, economically, and accurately. Below, we will introduce the relevant characteristics of ultrasonic flow meters for your reference.1. Introduction
1. Definition: Ultrasonic flowmeter is an instrument that measures flow by detecting the effect of fluid flow on ultrasonic beams (or ultrasonic pulses).
. 2. Principle: According to the principle of signal detection, ultrasonic flowmeters can be divided into propagation velocity difference method (direct time difference method, time difference method, phase difference method, and frequency difference method), beam offset method, Doppler method, cross-correlation method, spatial filtering method, and noise method. Ultrasonic flowmeter, like ultrasonic flowmeter, is an unobstructed flowmeter due to the absence of any obstruction in the instrument flow channel. It is a type of flowmeter suitable for solving the difficulty of flow measurement, especially in large-diameter flow measurement, and has outstanding advantages. It is one of the rapidly developing types of flowmeters. The ultrasonic flowmeter adopts the principle of time difference measurement: a probe emits a signal that passes through the pipe wall, medium, and the other side of the pipe wall, and is received by another probe. At the same time, the second probe also emits a signal that is received by the first probe. Due to the influence of the medium flow velocity, there is a time difference Δ t between the two. According to the calculation, the conversion relationship between the flow velocity V and the time difference Δ t
