Description:

1. Should the ultrasonic flowmeter in the fire pump room be wired? The handheld ultrasonic flowmeter used in the fire pump room does not require wiring. It adopts an external clamp installation, with the probe directly attached to the outer wall of the pipeline, powered by batteries, and can measure flow by inputting parameters such as pipe diameter and material when turned on. The entire process does not require pipe breakage, continuous water supply, or power cord connection. Fixed ultrasonic flow meters (such as pipe section or flange type) require wiring, including power lines, 4-20mA signal lines, or RS485 communication lines, for long-term online monitoring and data remote transmission. However, these devices are mostly used for new construction or renovation projects and are not for inspection scenarios. According to the spot parameters of Shanghai Fire Ultrasonic Flow Meter (DN50-DN500, Mingyu brand), portable models are commonly used for on-site testing, emphasizing "instant clamping and testing, instant testing and travel". The 15 hour battery life supports full day inspection, completely avoiding the difficulties of wiring construction.

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 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.

3. Monitoring Method for Flow and Velocity in Underground Wells

Monitoring the flow and velocity in underground wells is the core link of urban drainage network management, and its data accuracy directly affects the decision-making effect of flood prevention and drainage, sewage treatment, and waterlogging warning.

. The following is an explanation from three aspects: monitoring technology, equipment application, and installation principles:

1. Application technology principle of pipeline radar water level monitoring station: using a radar water level gauge with a beam angle of only 8 °, the water level height is calculated by emitting high-frequency electromagnetic waves and receiving reflected signals. Its non-contact measurement method can avoid the influence of water pollution or mechanical wear, and is suitable for complex underground e
