Hi, Great guide. I am looking into purchasing a TUF 2000-m. Would anyone with access to the control box be able to find the approximate transducer spacing for a stainless steel pipe with around a 4.5-inch(114.3 mm) and 4-inch pipe diameter (100 mm),  Pipe thickness of 0.25-inch (6.35 mm), using a V shape waveform using the TM-1 transducer and no liner? I am trying to get a range of the spacing for the transducers before purchasing the equipment

Thank you- very good description.
I am trying to set up my TUF-2000m.
I am having trouble getting a good quality reading. 
I have designed a 3d printed clip on adaptor to hold the TS-2 sensors to my 22mm pipe.
This should help with alignment. Keeps orientation yaw/roll/pitch constant, and allows me to micro adjust sensor spacing.
My Q value is poor.

I also note that if you look at the specification for copper pipe and its wall thickness, these have a tolerance. 
By trying the extreme tolerance values for the pipe in the TUF-2000 I saw a total sensor spacing variation of 0.57mm.
The actual spacing of the sensors may need to be adjusted to get an accurate reading.
Also note that the reaction of the TUF-2000 is not instantaneous, so calibration needs to be done after the flow reading has stabilized.
I move a bucket under the pipe outlet for 1 minute after the flow rate has stabilized and then measure its volume. 
I compare this to the flow rate given by the TUF-2000.
I came here looking for an answer to the temperature sensor. 
My TUF-2000 also reads 46C, but I notice this number does not change when I warm up the TS-2 sensors.
The TS-2 sensors do not have temperature sensing in them. 
You need to purchase two PT100 sensors (euro 4 each) and wire them to the TUF-2000 using pins 52,53 & 54.
I have yet to get my device to work to my satisfaction- but I keep experimenting!
Good luck with your.

hi. have you set up a zero flow on M42. On my application is a password, do you know the password?
Thank you!

Hallo, 
ich danke am Anfang mal für die Info die zu lesen sind.
Ich habe auch den TUF -2000M mit den Sensoren UP und DW sowie Netzteil 24 V neu zugelegt mit der Anleitung in English und versuche mich mal durchzukämpfen.
Unter Strom aber noch nicht an den Wasserleitungen angeschlossen und getestet. Es sind PVC Leitungen mit 20mm Außendurchmesser.
Noch allgemeine Info, benötige den TUF für Erdleitungen 2 x Vorlauf und 2 x Rücklauf zu bestimmen, das heißt, ich muß die 4 verschiedene Leitungen bestimmen und lokalisieren, bevor ich die durchtrenne muß ich wissen, welche 2 gehören zusammen?
Jeweils Vorlauf und Rücklauf und wie ist die Strömungsrichtung?
Kann mir jemand einen Tipp geben!

mfg Ernst

Thanks for a wonderful write up!
I'm trying to use the sibling of your device, the TUF-2000B, which is in a waterproof case intended for wall mounting.  All the parameters and steps you describe, however, are identical.  
Unfortunately, I am finding that for certain pipe parameters and transducer choices I get a negative mounting distance (M25).  Do you know why, and what I can do about it?
A sample: OD=22.2 mm, wall=0.81 mm, liquid=water, transducer=TS-2, mount method=V  result in a negative distance -1.7mm
Changing to method W results in a positive distance = 18.3 mm
