The installation of the Prosonic Clamp-On ultrasonic flowmeter is divided into two main parts: sensor installation and transmitter programming. This article focuses on the transmitter programming process, guiding engineering technicians to complete parameter configuration and commissioning.
1. Preparations Before Transmitter Programming
Before starting programming, confirm that the sensors have been correctly installed and wired. It is recommended to verify the following information to avoid subsequent parameter errors.
- Pipe material, outer diameter, and wall thickness
- Medium type, temperature, and sound velocity
- Sensor model and installation spacing
- Transmitter power supply and output signal type
Once ready, enter the programming menu via the transmitter panel or commissioning software.
2. Core Steps of Transmitter Programming
2.1 Enter Programming Mode
After power-on, the transmitter usually automatically enters the measurement interface. Press the E key or use the menu key to enter the main menu, then select "Setup" or "Quick Setup" to begin programming.
2.2 Enter Pipe and Medium Parameters
Follow the prompts to enter the pipe outer diameter, wall thickness, material, and medium sound velocity in sequence. These parameters directly affect flow calculation accuracy and must match the actual site conditions.
- Select pipe material (e.g., carbon steel, stainless steel, PVC)
- Enter pipe outer diameter and wall thickness
- Select medium type or manually enter sound velocity
- Confirm sensor installation method and spacing
2.3 Configure Outputs and Alarms
According to control system requirements, set the 4-20mA output, pulse output, or relay alarm. The range should match the actual flow range to avoid signal saturation.
| Parameter | Typical Setting | Description |
|---|---|---|
| Output Type | 4-20mA | Corresponds to instantaneous flow |
| Lower Range | 0 m³/h | Based on minimum pipe flow |
| Upper Range | Maximum flow | Recommend 10% margin |
| Alarm Method | Relay | Empty pipe or fault alarm |
3. Commissioning and Verification
After programming is complete, return to the measurement interface to check signal strength and signal-to-noise ratio. If the signal is weak, recheck the sensor installation spacing and couplant.
- Observe whether the flow display is stable
- Compare with actual operating conditions to verify accuracy
- Record key parameters for maintenance

4. Common Issues and Precautions
If no signal or abnormal readings occur during programming, prioritize checking sensor installation and parameter input. Ensure the pipe is full and free of bubbles; otherwise, ultrasonic propagation will be affected.
- Avoid installing sensors near pump outlets or valves
- Regularly check whether the couplant has dried out
- After modifying parameters, save and restart the transmitter
