Promag P Transmitter Overview
Promag P Transmitter is a high-performance signal conversion unit designed specifically for electromagnetic flowmeters, widely used in water treatment, chemical, food and beverage industries. Its core function is to convert the flow signal collected by the sensor into standard industrial signal output and support multiple communication protocols.
Based on the official Chinese manual, this article extracts key information to help you quickly understand the product's technical features, installation points, and operating specifications.
Core Functions and Features
- High-precision measurement: Typical accuracy up to ±0.2%, meeting strict industrial metering requirements.
- Multi-parameter display: Real-time display of flow rate, total volume, flow velocity, etc., with backlit LCD screen.
- Wide power supply range: Supports 85~265V AC / 20~55V DC power supply, adapting to different site conditions.
- Multiple output signals: 4~20mA, pulse/frequency, HART, Modbus, etc. optional.
- Protection class: Standard IP67, optional IP68, suitable for humid or submerged environments.

Installation and Commissioning Steps
Installation Points
- Ensure the sensor is full of pipe and the fluid direction is consistent with the arrow.
- The transmitter can be installed integrally or remotely; the remote cable length should not exceed 200m.
- Avoid installation in areas with strong vibration or strong electromagnetic interference.
- Strictly follow the terminal diagram when wiring, and separate power and signal lines.
Commissioning Process
- After power-on, check whether the display screen lights up normally.
- Enter the menu to set parameters such as meter factor, range, output type, etc.
- Perform zero calibration: ensure the pipe is full and the fluid is stationary.
- Analog output verification: use a multimeter to measure the 4~20mA corresponding flow value.
Common Issues and Precautions
- Large display fluctuation: Check whether grounding is good and whether the fluid contains bubbles.
- No output signal: Confirm power supply, fuse, and output configuration.
- Decreased accuracy: Recalibrate zero point and check whether electrodes are contaminated.
- It is strictly forbidden to open the transmitter housing while powered.
- Regularly check the sealing ring to prevent moisture intrusion.
