Review: Product works and the email product support was excellent. - Three weeks in -----Nice package and tool kit. Initial set up went ok. My first candidates were 1" copper type L pipes on a hot water return circulation loop. I used vaseline. The readings were weird - very low, zero and then they went negative and then positive. My M90 signal strength was not very good. I then got a 'Signal Reverse Error' and an error 0400 and it stopped reading. So I ordered some proper ultrasonic gel; no help. In the interim we replaced the pump (it was old) and when i broke it down we discovered the impeller had no blades on it - hence the negative readings. I sent the vendor all the info and some pix and they got back to me overnight - had me reset to original factory specs and I set everything up again and this time I used the proper gel - they said alway reapply anytime you move it. Worked perfectly. I still get the 'Signal Reverse Error' sometimes if I leave the sensors in place too long on a hot pipe - it dries up. So i add another dab and it works fine again. So far very happy with it.
Review: error code G5N_H2 - How do i clear this error code? I got my meter today and it does not work.

## Features

- S1+M2 TRANSDUCERS: Easy to setup the transducers on the pipe and enter the required information in the control unit.No need to destroy the pipeline and stop production during the measurement process.S1(DN15-100mm, 1/2-4"), M2(DN50-700mm, 2-28")
- DIGITAL DISPLAY: The Ultrasonic Flowmeter can display cumulative flow, instantaneous flow, velocity, and working status at the same time. Accuracy: 1%, linearity: 0.50%, repeatability: 0.20% accuracy: ±1%, calibration certs included. Note: Couplant is not included because the international transport limit, you can use butter, petroleum jelly, dish soap, etc. instead.
- DATA STORAGE AND OUTPUT: This Ultrasonic Flow Meter has a built-in data logger, which can store up to 2000 lines of measurement data. And you can download the logged data onto PC through the RS232 interface.
- LONG STAND TIME: This Flow Meter is equipped with a built-in high-capacity rechargeable battery, which can support the flowmeter to work continuously for up to 12 hours.
- WIDE APPLICATION: Come with S1+M2 transducers, and the measuring range is DN15-700mm, 1/2-28". It can work on Copper pipe, PVC pipe to detect the flow of liquids such as sea water, alcohol, river water, industrial sewage, lubricating oil, diesel, fuel oil, etc.Not suitable for rubber pipe, SAE30 hydraulic fluid.

## Questions & Answers

**Q: I am not seeing all parameters (including one to set the fluid type) and am also not able to do a factor reset.  Need password or way to unlock?**
A: M20 Window is for selecting fluid type.
It is simple to enter the menu, you only need to press the MENU button, and then enter the number to enter the corresponding window. Press ENTER button to modify.

**Q: Will this provide Peak flow rate data? I'm trying to consider this as tool to size water treatment equipment and peak flow rate is required?**
A: Hi, this product can only provide a series of data and one data at a time. And all of data should be recorded manually.

**Q: What straight run requirements does this meter need?  How many pipe diameters of straight pipe do I need upstream and downstream of the sensors?**
A: The tested pipeline needs to be a dense medium that can transmit ultrasonic waves, such as stainless steel, carbon steel, copper pipe, PVC, FRP, PPR, etc. After you input outer circumference (M10) or input pipe diameter (M11), wall thickness (M12), installation method (M24), and then automatically calculate the transducers spacing(M25).

**Q: Can I use it with carbon or stainless steel? or Do I need other sensors?**
A: Yes, it can use with carbon or stainless steel, and the ultrasonic flowmeter come with S1+M2 transducers, and the measuring range is DN15-700mm (1/2-28") .

### ⭐ error code G5N_H2

How do i clear this error code? I got my meter today and it does not work.

### ⭐⭐⭐⭐⭐ Eficacia, calibracion y datos correctos.
*by G***O on January 6, 2026*

Es el segundo equipo que tenemos, ha funcionado el primero perfectamente, se pudo calibrar con ISO 17025, es eficaz y hasta ahora no me ha fallado, lo rcomiendo sin dudar. Lo unico que debo probar es el programa para bajar los datos ya que el primero no pude instalarlo por algun tema de persmisos en mi computadora, este segundo viene con USB, voy a tratar de instalarlo en cuanto lo use. Seria bueno tener un case o protector para el equipo.
