Panametrics PM880 Ultrasonic Flowmeter
Intermediate Technical Document | Revision 1.0 | Date: 2026-02-28
1. Device Overview
The Panametrics PM880 is a high-performance ultrasonic flowmeter designed for accurate measurement of liquid flow rates in industrial applications. It features non-intrusive measurement technology, ensuring no pressure loss and minimal maintenance requirements.
Key advantages include wide flow range capability, high accuracy (±0.5% of reading), and compatibility with various pipe materials and sizes (DN15 to DN6000).
2. Technical Specifications
Measurement Principle
Transit-time ultrasonic
Operating Temperature
-40°C to +180°C
Power Supply
100-240V AC (50/60Hz) or 24V DC
Output Signals
4-20mA, RS485 (Modbus RTU), Pulse, Alarm
IP Rating
IP67 (sensor), IP65 (transmitter)
Response Time
0.1 to 10 seconds (configurable)
3. Basic Operation Steps
1 Power on the PM880 transmitter and wait for the self-test to complete (approx. 30 seconds).
2 Access the configuration menu by pressing the “MENU” button on the front panel.
3 Enter pipe parameters (material, diameter, wall thickness) and fluid properties (temperature, type).
4 Calibrate the sensor alignment using the “CALIBRATE” function to ensure optimal signal strength.
5 Save configuration and exit to the main display to view real-time flow rate and totalized values.
Important Notes
- Ensure the sensor is installed on a straight pipe section (minimum 10D upstream, 5D downstream) to avoid flow disturbance.
- Regularly check signal strength (minimum 25 dB recommended) to maintain measurement accuracy.
- Do not expose the transmitter to extreme voltage fluctuations; use a surge protector if necessary.
- Calibration should be performed annually or after any major pipe modification.
