Tommy the TTFM and his friends have been out causing mischief again with Marc Richards over the last couple of weeks.

At a borehole site in Gloucestershire, it was required to monitor the flow from a 225 mm MDPE pipe measuring the flow from a borehole.  Unfortunately, after some trial and tribulations, Tommy was unsuccessful on this application – so he gave itTommy on pipe number 1 up and let his friend Daisy the DFM have a go and unfortunately, she did not get any luck either.

It was decided that the pipe perhaps wasn’t suitable for the pair, so after a short while and some adjustments from Marc in regard to sensor placement and parameter settings – it was agreed they would try a different pipe.

Pipe number 2As a result, a different pipe was uncovered, and this time it was 180 mm OD MDPE and Tommy was the first to try again. The average flow in this pipe was thought to be around 11.7 l/s – however it just was not Tommy’s day that day and he failed to acquire the flow rate.  However, Marc still had Daisy the DFM as a backup!

Marc decided to set Daisy the DFM up, which was simple and easy to do as both systems just need to be strapped to the outside of a pipe to see if she could receive anything.

SUCCESS! Daisy did manage to get some flow readings, and the valve within the process was opened and closed, reducing, and increasing the flow rate to see if Daisy could reflect this in her readings. Unfortunately, when the flow reached around 8 l/s Daisy’s reading fell to 0 – Marc thought this was not due to Daisy measuring the flow, but more so that the pipe was not full enough.

However, they managed to get the stable reading back again when the valve was opened and Daisy was reading a strong 11.4 l/s the site technicians confirmed this was a good reading by monitoring the flow elsewhere on the process.

After some trial and error, lots of hole digging and pipe searching, Daisy the DFM proved successful this time. Overall, the customer was pleased and impressed with the technical knowledge of Marc Richards our Test and Technical Support DFM readingsEngineer and are considering investing in a portable version of Daisy, to help test flow conditions on various sites.

Another successful application for Tommy and his friends.
