good shopping experience, thanks

I just bought this tool, pls ship it to me son, I need it urgently

We can use this solve many problems for our customers at full speed. Next time, I will come back to buy an additional one if necessary.

I work at a small water district and we have had need of an ultrasonic flow meter in the past to detect water leaks. We have used a Fuji flow meter available from an agency that helps small districts find water leaks. The Fuji meter is out of our price range at around $6000+, so when we found this meter we thought it was worth a shot. We made a test flow pipe with a water meter attached to the incoming end to monitor flow amount, and a variable discharge to control the flow at the downstream end.

Once the TDS was set up and calibrated we checked the flow through the 2" line and it was almost exactly what the water meter indicated as flow amount, within .1 gallon per minute. The TDS meter was consistent for the one hour test and based on this initial performance we are pleased with the results. Although the hand held unit is less substantial than the Fuji it seems to have all of the same features. Set up was relatively strait forward once a few pieces of information were obtained (pipe sizing chart can be found online). The aluminum case and associated hardware that comes with the TDS seem to be of good quality. The only issue so far is that I get a "no signal received" when trying to use the small sensors (HS), but I think that is due to not keying in the correct information at set-up (reason I did not give it five stars). The HM sensors work perfectly thus far.

We will be taking the meter out to the field for leak detection next week and will hopefully have the Fuji meter right along side to compare to. I suspect the readings will be comparable. For our purposes the amount of flow is secondary to actual flow detection since we are trying to isolate leak areas rather than monitor flow amount, but want the meter to be reasonably accurate so that we will know how much water is passing a given point in the line.

I will post more on this instrument as we use it under actual real world conditions. So far, so good.............

always cheaper than Amazon,but the quality is very good.Thank you

thanks, received the tool

This meter works just as well as meters which are more expensive. thanks

can you ship it by DHL?to US

Do you have examples of data logger output for the TDS-100H_M2+S1 Ultrasonic flow meter?

Dear Mrs,
I need the best price for the sensors S1 M2 and L1,
and TDS 100H

Can I just buy sensors from you?

Working well

Product is of good quality
