P116 Ultrasonic Flowmeter
Portable Transit-time Ultrasonic Flowmeter — Version 3.1.0
Applications and measurement
Portable clamp-on flow measurement for homogeneous liquids in pipes from 25 to 600 mm. Applications include process water, cooling water, water treatment, aquaculture, HVAC and irrigation.
The rechargeable battery provides up to 10 hours of operation when fully charged. A backlit 2.8-inch display and TF-card logging support temporary measurements and data collection.
About P116
The P116 version 3.1.0 is a handheld transit-time ultrasonic liquid flowmeter with CP036 magnetic portable transducers. It measures flow from outside the pipe without cutting into it.
- Accuracy: ±1% of measured value at 0.5–5 m/s.
- Repeatability: 0.2%.
- Pipe size range: 25–600 mm.
- Measurable flow velocity: ±0.01–±5 m/s.
- Memory data logging: 16 GB TF card; at least 1,000 data files.
- Display: 2.8-inch TFT black and white screen, 240 × 320, with backlight.
- ARM processor and low-voltage wide-pulse transmission.
- Automatic measuring circuitry with no manual tuning; 16-key interface.
Application and Installation Guidance
Liquid and pipe suitability
Suitable for homogeneous liquids; exclude high concentrations of suspended particles or gases. Magnetic attachment is intended for magnetic metal pipes; pipe straps are included in the kit.
The ordering specification lists carbon steel, stainless steel, PVC and copper pipes. Confirm pipe and liquid suitability for the application.
Measurement location
Allow the straight lengths shown in the installation site drawings. Avoid the 6 and 12 o’clock positions, where sediment or bubbles can weaken the signal.
Prefer pipe sections without internal scaling. If scaling cannot be avoided, account for it as a lining when configuring the meter.

Transducer Installation Methods
V Method
V method: 25–400 mm pipe, with both sensors on the same side, horizontally aligned and parallel to the pipe axis.
Z Method
Z method: 100–600 mm pipe, with sensors on opposite sides. Avoid the top and bottom of the pipe. The catalogue recommends Z installation for pipes of 300 mm and above.
Installation Site Selection
Minimum straight lengths (upstream / downstream): 90° bend 10D / 5D; tee 50D / 10D; diffuser 30D / 5D; reducer 10D / 5D; valve 30D / 10D; vertical pipe 10D / 5D; pump 50D after the pump. D is pipe diameter.
