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.

The core content of the Chinese manual for TDS-100P portable ultrasonic flowmeter is as follows:

1. Product Overview TDS-100P portable ultrasonic flowmeter is a high-precision, non-contact flow measurement instrument suitable for measuring the flow rate of liquids in closed pipelines.

. It adopts the principle of ultrasonic time difference method, which calculates the flow velocity by measuring the time difference between the forward and backward propagation of ultrasonic waves in the fluid, and then obtains the flow rate value. This product has the advantages of easy installation, accurate measurement, and good stability, and is widely used in fields such as petroleum, chemical, water conservancy, and environmental protection.

2. Main functional features: High precision measurement: The measurement accuracy can reach ± 1%, and the repeatability is better than ± 0.5%, meeting most industrial measurement needs.

. Non contact measurement: No need to damage the pipeline, easy to install, suitable for pipelines of various materials. Wide range ratio: The range ratio can reach 1:100, suitable for measurement scenarios with different flow rates. Multiple signal outputs: Supports 4-20mA current signals, RS485 communication interfaces, etc., making it easy to connect with the upper computer system. Data storage function: Built in large capacity storage, capable of storing a large amount of measurement data for subsequent analysis. Portable design: small size, light weight, easy to carry and operate on site.

3. Instructions for use: Install and prepare to check whether the appearance of the flowmeter is intact and whether the accessories are complete.

. Select the appropriate sensor installation method (such as external clamp, insertion, etc.) based on the material and diameter of the pipeline. Clean the surface of the pipeline to ensure good contact between the sensor and the pipeline. When installing an external clamp sensor, align the sensor with the pipeline and secure it with a special clamp to ensure a tight fit between the sensor and the pipeline. When installing a plug-in sensor, it is necessary to drill holes in the pipeline, insert the sensor into the pipeline, and seal it with se
