OUSTF10 Product Overview
The OUSTF10 is an ultrasonic flowmeter suitable for flow measurement of water, sewage, seawater, and various homogeneous liquids. It adopts the time-difference measurement principle and features non-contact measurement, low pressure loss, and a wide turndown ratio, and is widely used in water supply, environmental protection, chemical, and energy metering scenarios.
Core Advantages
- Non-contact measurement: The sensor is clamp-on or insertion-mounted, without damaging the pipe and with no additional pressure loss.
- Wide turndown ratio: It can cover low-flow and high-flow conditions with strong adaptability.
- Display and output: It supports instantaneous flow and cumulative flow display and provides multiple signal outputs.
- Reliable protection: The transmitter and sensor protection ratings meet the requirements of on-site humid and dusty environments.

Installation Steps
Correct installation is the prerequisite for ensuring the measurement accuracy of the OUSTF10. Please follow the steps below and ensure the pipe is full and the fluid is stable.
- Confirm the pipe material, pipe diameter, wall thickness, and medium information, and select the appropriate installation method (clamp-on or insertion type).
- Select straight pipe sections: upstream ≥10D, downstream ≥5D, avoiding disturbance sources such as valves, elbows, and pump outlets.
- Clean the pipe surface, apply couplant, fix the sensor, and ensure the opposite-transmission spacing is accurate.
- Connect the transmitter and sensor cables, and connect the power supply and output signals according to the wiring diagram in the manual.
- After power-on, enter the menu and set parameters such as pipe diameter, wall thickness, medium, and units.
- Observe the signal strength and flow velocity display, and fine-tune the sensor position if necessary until the signal is stable.
Commissioning and Maintenance Points
Commissioning Suggestions
- Prioritize using signal strength and signal-to-noise ratio indicators to judge installation quality.
- Zero calibration should be performed under full-pipe, static fluid conditions.
- Record and back up parameter modifications for fault recovery and batch replication.
Daily Maintenance
- Regularly check whether the sensor couplant has dried out and reapply it if necessary.
- Keep the transmitter wiring terminals dry to prevent signal drift caused by moisture.
- After long-term operation, recheck the cumulative flow and compare it with process data to detect abnormalities in time.
Common Problems and Selection Tips
Common on-site problems include weak signals, fluctuating readings, and no output. Most cases are related to insufficient straight pipe sections, poor coupling, or incorrect parameter settings, and can be checked one by one according to the manual.
When selecting a model, please focus on pipe diameter, medium temperature, output method, and protection rating, and reserve communication interfaces for connection to SCADA or energy management systems.
