In engineering projects, the correct installation and maintenance of HD-MLF-100 and SYTFTDS-100F ultrasonic flow sensors are of critical importance. As a professional supplier of flow control equipment, Xi'an Shenghongchuang Instrumentation Co., Ltd. provides you with detailed guidance to ensure efficient sensor operation. Whether you are a project manager or a distributor, mastering these key points can improve engineering efficiency and equipment service life.
I. The Core Value of Ultrasonic Flow Sensors in Engineering Projects
Ultrasonic flow sensors such as HD-MLF-100 and SYTFTDS-100F have become the preferred choice for industrial flow monitoring due to their non-contact measurement, high accuracy, and anti-interference capability. Their wall-mounted design is suitable for complex scenarios with pipe diameters ranging from 50mm to 6000mm, and is especially suitable for long-term stable operation in water treatment, chemical, energy, and other fields. Test data from Xi'an Shenghongchuang Instrumentation Co., Ltd. shows that properly installed sensors can control measurement error within ±1%, greatly reducing process risks caused by data deviation.
II. HD-MLF-100 Ultrasonic Flow Sensor Installation Specifications
1. Installation Location Selection
• The upstream straight pipe section length must be ≥10 times the pipe diameter, and the downstream must be ≥5 times the pipe diameter (for example, a DN200 pipeline requires more than 2 meters of reserved space)
• Avoid turbulence sources such as pumps, valves, and elbows to ensure the fluid fills the pipe and is free of air bubbles
• Horizontal pipelines are preferred; for vertical installation, an upward flow direction must be set
2. Key Points for Sensor Fixing
• Use the matching clamp to tightly attach the HD-MLF-100 to the pipe wall, and apply the coupling agent evenly without gaps
• The axial distance between the two sensors must be set strictly according to the menu parameters L1/L2, with an error of ≤0.5mm
• Cable routing must be kept away from high-power equipment, and metal conduits should be used to shield interference
III. Maintenance and Troubleshooting of the SYTFTDS-100F Sensor
This model adopts a dual-probe redundancy design, and routine maintenance should focus on:
• Monthly inspection: remove deposits from the probe surface and check the sealing performance of the O-ring
• Quarterly calibration: correct K coefficient deviation by comparing with reference flowmeter data
• Typical fault handling: when the signal strength is below 60%, readjust the probe angle; if the instantaneous flow rate fluctuates, check whether the grounding resistance is ≤4Ω

V. Three Major Measures to Improve Sensor Service Life
1.Environmental control: keep the humidity of the installation environment at ≤85%RH, and avoid direct sunlight causing LCD aging
2. Power management: configure a UPS uninterruptible power supply to prevent surge impact from damaging the circuit board
3. Data tracking: establish equipment health records through the supporting TC-GD data logger
