Prosonic Clamp-on Flowmeter Transmitter Programming Overview
Prosonic clamp-on ultrasonic flowmeter can only be put into normal operation through transmitter programming after sensor installation is completed. The core of transmitter programming is inputting pipe parameters, medium parameters, and output configuration so that the instrument matches the actual working conditions. This section follows the installation part and focuses on explaining the transmitter programming process and key settings.
Preparation Before Programming
Confirm Installation Status
- Check whether the clamp-on sensor has been fixed at the correct position on the pipe according to installation specifications.
- Confirm that the coupling agent is applied evenly, with no bubbles or drying.
- Verify that the sensor spacing is consistent with the pipe diameter and wall thickness parameters.
Prepare Necessary Parameters
- Pipe outer diameter, wall thickness, and material.
- Medium type, temperature, and sound velocity range.
- Output signal type: 4-20mA, pulse, or bus communication.
Main Steps of Transmitter Programming
Enter the Programming Menu
- Power on the transmitter and wait for self-check to complete.
- Enter the main menu via keys or debugging software.
- Select "Quick Setup" quick setup wizard.
Enter Pipe and Medium Parameters
- Enter the pipe outer diameter and wall thickness; the instrument automatically calculates the inner diameter.
- Select the pipe material and lining type.
- Enter the medium type and operating temperature.
- Confirm that the sensor installation method is clamp-on.
Configure Output and Display
- Set the upper and lower range limits, corresponding to the 4-20mA output.
- Configure the pulse output equivalent or bus address.
- Set the damping time to stabilize readings.
Key Parameter Reference Table
| Parameter Item | Typical Setting | Description |
|---|---|---|
| Pipe outer diameter | Input according to actual measurement | Affects sound path calculation |
| Wall thickness | Input according to actual measurement | Affects inner diameter and sound velocity |
| Medium sound velocity | Look up according to medium | Determines measurement accuracy |
| Damping time | 3-10 seconds | Suppresses fluctuation |
Verification and Optimization After Programming
Signal Quality Check
- Check the signal strength and signal-to-noise ratio indicators.
- If the signal is weak, check the coupling agent and sensor position.
- Confirm that the flow rate reading matches the actual working conditions.
Common Problem Handling
- Large reading fluctuation: increase damping time or reinstall the sensor.
- No signal: check cable connections and whether parameters are incorrect.
- Accuracy deviation: recheck pipe parameters and medium sound velocity.
After completing the above programming and verification, the Prosonic clamp-on flowmeter can stably output flow signals to meet engineering measurement and monitoring requirements.
