## Questions & Answers

**Q: Will this unit work on PE Pipe?**
A: Yes, this ultrasonic flowmeter can work on PE Pipe with pipe thickness less than 8mm(0.31inch).

**Q: What is the minimum flow rate?**
A: Hello,
The measurable flow speed ranges from 0.1m/s to 6m/s, and the flow rate needs to be calculated based on the diameter of the pipeline, and the pipeline needs to be full.

**Q: Is the batery replacable and where would I send it to calibrate it**
A: The battery of this ultrasonic flowmeter is a Ni-MH rechargeable battery with a service life of 1-2 years and does not support replacement. If you need it, you can search for "3.6V 2000mAh Ni-MH Battery" to buy.
As for calibration, the machine is already calibrated at the factory and does not need to be calibrated.

**Q: will it give instant readings GPM on the handheld or do i need softwear?**
A: Hello, the handheld flowmeter will display the real-time reading of GPM, but if you need the measurement data in the past period of time, you need to use the software.
