Facing the challenge of selecting the YSD100P/YSD100H/YSD100Y ultrasonic flow sensor series？This article clearly shows the core differences of the three products through a comparison table，helping technical evaluators quickly match project requirements。Xi'an Shenghongchuang Instrument and Meter Co., Ltd. is a professional sensor manufacturer，its clamp-on ultrasonic flow sensors are known for high precision and stability。

一、Product series definition and key application scenarios

The YSD100 series is an industrial flow monitoring solution designed for non-invasive measurement，using the time-difference ultrasonic principle and meeting ISO 6416 standards。Among them，YSD100P is targeted at fixed pipeline installation scenarios，with the protection rating reaching IP68；YSD100H optimizes the sensor materials for high-temperature media（up to 120℃）；YSD100Y integrates 4-20mA+HART protocol output for integration into DCS systems。In industries such as petrochemicals，municipal water supply，and HVAC systems，this series can replace traditional mechanical flowmeters and achieve ±1% measurement accuracy。

二、Technical parameter comparison analysis

三、Key factors for selection decisions

Technical evaluators should focus on three dimensions：first，media characteristics，for corrosive fluids the special alloy probe of YSD100H should be selected；second，system compatibility，PLC-integrated projects should use the HART protocol of YSD100Y；finally，installation environment，long-term immersion conditions require selecting YSD100P with IP68 protection。It is worth noting that all three products have passed CE certification and RoHS testing，and are superior to competitors such as NZ-TDS-100H in electromagnetic compatibility。

四、Industry application case validation

In a Shaanxi co-generation project，18 units of YSD100H successfully replaced the original NZ-TUF-2000S equipment，achieving zero-failure operation for 8000 hours in 90℃ high-temperature condensate measurement。Another typical case is GR-CSB-1000 in a municipal water network application，where matching with YSD100P reduced leakage rate from 22% to 9%。These practices confirmed that this product series has reliability advantages under extreme operating conditions。

五、Common technical misconception analysis

Misconception 1：assuming all ultrasonic flowmeters are suitable for fluids containing bubbles。In fact，the YSD100 series needs to be used together with our bubble suppression algorithm；Misconception 2：ignoring pipe material impact。For copper-iron pipelines，it is recommended to use the enhanced signal processing chip of YSD100Y；Misconception 3：underestimating installation requirements。A straight-pipe section of 10D before and 5D after must be ensured，and this point also applies to similar products such as JC100A。

Why choose Shenghongchuang Instruments

As a national high-tech enterprise，we own 12 ultrasonic measurement-related patents，and all products pass a 72-hour aging test before leaving the factory。Compared with imported brands such as XA98-XI，we provide localized rapid-response service and can reach major industrial zones nationwide within 48 hours。If you need the full technical solution document for the YSD100 series，please call 029-XXXXXXX to contact our engineering support team。
