As core products for flow control equipment，the WK-100P，WK-100H and WK-100F series ultrasonic flow sensors provide professional solutions for different application scenarios。This article will help technical evaluators accurately select the appropriate model from dimensions such as technical parameters，installation methods and environmental adaptability，improving the efficiency and accuracy of flow monitoring。

I、Product Definition and Technical Overview

The WK series ultrasonic flow sensors adopt the transit-time measurement principle，accurately calculating flow velocity and flow rate by detecting the time difference between downstream and upstream ultrasonic propagation in the fluid。This series of products complies with the ISO 6416 international standard，with measurement accuracy up to ±0.5%，and is suitable for various media such as water，oil and chemical reagents。Among them，WK-100P is a pipeline-mounted installation model，WK-100H adopts a wall-mounted design，and WK-100F is a split-type structure。All three models support the Modbus RTU communication protocol and can be seamlessly integrated into industrial automation systems。

II、In-depth Analysis of Application Scenarios

In municipal water supply systems，the WK-100H wall-mounted ultrasonic flow sensor，with its IP68 protection rating and -20℃~60℃ operating temperature range，is especially suitable for humid environments such as underground utility tunnels。For high-temperature medium measurement in the petrochemical industry，the split-type design of the WK-100F allows the sensor and transmitter to be installed separately，preventing electronic components from being exposed to high-temperature environments above 80℃。For hygienic pipelines in the food and pharmaceutical sectors，the 316L stainless steel version of the WK-100P is recommended。Its surface roughness Ra≤0.8μm meets GMP certification requirements。

IV、Selection Guide and Common Misconceptions

Technical evaluators need to pay special attention to the impact of medium conductivity on ultrasonic measurement。Although the WK series can theoretically measure non-conductive liquids，in practical applications，media with conductivity ≥5μS/cm are recommended as the preferred choice。Another common misconception is ignoring pipeline vibration interference。When strong mechanical vibration exists in the installation environment，the dedicated vibration-damping bracket equipped with the WK-100F should be selected。In addition，for large-diameter pipelines above DN300，dedicated installation fixtures such as the JGTUF-2000S are required to ensure measurement stability。
