As a professional evaluator in the field of flow control equipment, are you looking for a TC-SC wall-mounted ultrasonic flow sensor with outstanding performance? This article will provide an in-depth analysis of the 5 core performance indicators that technical experts care about most, helping you evaluate the key differences among mainstream models such as SYTFTDS-100P and HD-TUF-2000. With many years of industry experience, Xi'an Shenghongchuang Instrumentation Co., Ltd. reveals the key points for selecting ultrasonic flow sensors for you.

I. Overview of Ultrasonic Flow Sensor Technology

Ultrasonic flow sensors accurately calculate flow rate by measuring the transit time difference of ultrasonic waves propagating through fluids. Their non-contact measurement characteristics give them significant advantages in corrosive, high-viscosity, or high-temperature media. The TC-SC series products developed by Xi'an Shenghongchuang Instrumentation Co., Ltd. adopt composite technology combining the Doppler effect and the transit-time method, covering a pipe diameter range of DN15-DN6000 and meeting the dual standard requirements of ISO 6416 and JJG 1030. Compared with traditional mechanical flowmeters, this type of equipment features no pressure loss, maintenance-free operation, and high accuracy (±0.5% of reading), making it especially suitable for long-term monitoring needs in industries such as chemicals, water treatment, and energy.

II. 5 Core Indicators Technical Evaluators Focus On

1. Measurement Accuracy and Repeatability

When comparing models such as SYTFTDS-100P and HD-TUF-2000, the focus should be on their calibrated accuracy (usually marked as "±% of reading") and repeatability error (generally required to be ≤0.2%). For example, the KATflow 200 series uses an adaptive signal processing algorithm and can still maintain ±1% measurement accuracy under low flow velocity conditions (0.03m/s), while UFLO2000 improves repeatability to 0.15% through dual-channel cross-validation technology. It is worth noting that actual accuracy is greatly affected by installation conditions, and on-site verification is recommended with reference to the IEC 60041 standard.

2. Media Compatibility

Different models show significant differences in compatibility with media characteristics: ABDT-LCT-S uses a specially coated probe that can withstand corrosive liquids with a pH value of 2-12; GLP-TDS-100H has a built-in bubble identification function and is suitable for liquid measurement with gas content ≤5%. The technical team needs to match the sensor type according to parameters such as medium conductivity, turbidity (NTU value), and solid particle content. For example, the SEAN UFT series specifically optimizes the echo processing algorithm for water with high sand content.

3. Environmental Resistance

Wall-mounted installation requires the equipment to have a protection rating of IP67 or above. Our TC-SC sensor adopts a 316L stainless steel housing and has passed wide-temperature testing from -40℃ to +85℃. In terms of electromagnetic compatibility, all models comply with the GB/T 17626.4-2018 standard, with measurement deviation ≤0.3% under 3V/m radio-frequency field interference. For explosion-proof scenarios such as petrochemicals, it is recommended to choose the HD-TUF-2000 explosion-proof model that complies with ATEX/IECEx certification.

4. Communication and System Integration

Modern ultrasonic flow sensors need to support multiple industrial protocols: MODBUS-RTU (RS485), HART, PROFIBUS DP, etc. SYTFTDS-100P innovatively integrates a 4G wireless transmission module, which, together with the Shenghongchuang cloud platform, enables remote diagnostics. During evaluation, attention should be paid to protocol compatibility, data refresh rate (up to 1Hz), and whether SDK secondary development is supported—this is crucial for DCS system integration.

5. Long-Term Stability and Maintenance Cost

According to third-party test data, the drift rate of high-quality sensors should be <0.1%/year. Our products adopt a self-cleaning probe design, and with online diagnostic functions, the calibration cycle can be extended to 5 years. In actual procurement, it is recommended to calculate TCO (total cost of ownership), including: initial purchase cost, installation and commissioning cost, periodic calibration cost (with reference to the JJG 1030 cycle), and spare parts replacement cost. For example, the 5-year warranty provided by the KATflow series can significantly reduce later operation and maintenance expenditures.

IV. Common Selection Misunderstandings and FAQ

Q: Are all liquids suitable for ultrasonic measurement?
A: Although in theory any sound-conducting liquid can be measured, media containing a large amount of bubbles （＞10%） or solid particles （＞5%） require special treatment. Our engineering team can provide media compatibility pre-evaluation services.

Q: How should wall-mounted and pipe-section types be selected?
A: The pipe-section type (such as GLP-TDS-100H) is suitable for newly installed pipelines and offers higher accuracy; the wall-mounted type (TC-SC) is suitable for retrofit projects, with installation costs 30%-50% lower.
