The HR-TUF wall-mounted ultrasonic flow sensor，with its fast installation feature，has become the ideal choice for industrial flow monitoring。This guide will detail how to complete the installation and commissioning of the HR-TUF sensor within 3 minutes，helping technical evaluation personnel quickly master the operating techniques of this high-performance flow sensor。

一、Product definition and core advantages

The HR-TUF series is a non-intrusive flow measurement device that complies with the ISO 6419 standard，using time-difference ultrasonic technology to achieve a measurement accuracy of ±0.5%。Compared with traditional mechanical flowmeters，its no-moving-parts design can reduce maintenance costs by 90%。Xi'an Shenghong Chuang Instrument and Meter Co., Ltd. integrates a DSP digital signal processing chip，enabling the product to keep stable output under severe working conditions such as strong vibration and high viscosity，making it especially suitable for measuring corrosive media in industries such as chemical and metallurgical processing。

二、Installation process breakdown

Step 1：Pipe segment pre-treatment - Use sandpaper to abrade the measurement area of DN50-DN300 pipe walls，ensuring that the surface roughness is ≤6.3μm。For products in the same series such as HY-TUF-2000P，special attention should be paid to removing the oxidation layer to ensure ultrasonic signal penetration。

Step 2：Sensor positioning - Determine sensor spacing according to the pipe diameter table（see table below），when fixing the probe with a magnetic clamp，ensure the axes of the two probes and the pipe axis are at an angle of about 3°。This technique is also suitable for wall-mounted ultrasonic flow sensors and hand-held ultrasonic flow transmitters such as SDUF-2000H。

三、Technical parameter comparison analysis

By comparing with similar products such as UHCSHL-2000H，HR-TUF has advantages in the following key indicators：flow velocity coverage from 0.03 to 12m/s；IP68 protection grade suitable for outdoor installation；its built-in temperature compensation module can work stably in an environment of -30℃~80℃。These characteristics make it an upgraded replacement solution for the wall-mounted ultrasonic flow sensor hand-held ultrasonic transmitter ZY-TUF-2000B。

四、Typical application scenario analysis

In a case at a large thermal power company in Shaanxi，20 HR-TUF sensors were used for steam pipeline monitoring，with data uploaded to the central control system through Modbus RTU protocol。Compared with the previously used HPLS series products，installation time was reduced by 70%，and the measurement drift problem caused by condensate interference was solved。This quick deployment feature is also suitable for the water utility application scenarios of the HQ-120 wall-mounted ultrasonic flow sensor hand-held ultrasonic transmitter。
