Introduction

In the water supply system flow monitoring field，HY-TUF-2000P and 2000S are the two mainstream wall-mounted ultrasonic flow sensors，and their performance differences directly impact system stability。This article will conduct a professional comparison from dimensions such as accuracy grade、environmental adaptability and so on，helping technical evaluators select the most suitable ultrasonic flow transmitter solution for projects。

1. Product overview and core parameter comparison

HY-TUF-2000P and 2000S are both high-precision wall-mounted ultrasonic flow sensors developed by Xi'an Shenghongchuang Instrument and Meter Co., Ltd.，using a non-contact measurement principle，suitable for liquid flow monitoring for pipe diameters of DN15 to DN600。Both units support 4-20mA analog output and RS485 digital signal transmission，but key parameters have obvious differences：

Compared with similar products such as ZY-TUF-2000B or HQ-120，the 2000S series shows more prominent performance in stability under extreme environments，and its special alloy transducer can withstand corrosive liquids with pH 2-12。

2. In-depth analysis of accuracy and stability

2.1 Dynamic flow compensation technology

HY-TUF-2000S is equipped with a third-generation DSP digital signal processor，and through real-time dynamic compensation algorithms can keep measurement fluctuation under vortex-flow conditions within ±0.3L/min。Test data show that within the flow velocity range of 0.3-10m/s，its repeatability error is more than 30% better than competitors such as PN-TUF。

2.2 Long-term drift control

2000P uses a standard temperature compensation module，annual drift about 0.2%，while 2000S uses an internal dual-channel reference calibration system，reducing annual drift to below 0.05%。For projects that need to meet ISO4064 Class 2 standard，2000S is the more reliable choice。

3. Environmental adaptability and installation optimization

3.1 Anti-interference design comparison

The electromagnetic compatibility of 2000S reaches the EN61000-6-4 industrial-grade standard，and can work stably within 3 meters around variable-frequency drives。Its proprietary acoustic wave path self-correction function can automatically compensate for the signal attenuation issue commonly seen in HR-TUF and similar equipment in vibrating pipelines。

3.2 Installation compatibility

Both products support multiple installation methods such as the V method and Z method，but 2000P has stricter probe spacing requirements（needing a straight section of 10D in front and 5D behind）。In contrast，the intelligent guidance mode of 2000S can automatically adapt to complex pipe layouts such as UHCSHL-2000H。

4. Economic and full life-cycle cost

Although the procurement cost of 2000S is 15%-20% higher than 2000P，the five-year total maintenance cost can be reduced by 40%：

• 2000S probe life reaches 10 years（2000P is 6 years）
• Support remote diagnostics，reducing on-site maintenance frequency
• Modular design lowers spare parts replacement costs by 50%
