Portability of Electromagnetic Flow Meter enables a Colorado City to track multiple Valves

Singer Valve

A city in Colorado needed to determine the flow through each of their three separate valve chambers to determine whether the water load was shared equally among the valves.   By measuring the flow rates, the operator is able to use the data to determine whether they need to adjust the pressure set points on any of the pressure reducing valves in each vault.  As there was no power source and limited space in the station, the client specifically wanted a portable flow meter that could be shared between three valves in the three separate chambers.

Pipestone Equipment’s, Dave Buchwald suggested Singer Valve’s SPI-MV as the unique single point insertion probe can be inserted into a Singer valve to measure flow and then removed and moved to a different valve. The insertion probe extends into the flow stream, in one of the valve inlet connections and protrudes into the valve, equivalent to 1/8 of the valve diameter size. As a single piece design, the bullet nose profile has no moving parts to get clogged and contains nothing to wear or break.

With the addition of the SPI-MV having the option of both AC and DC power and a compact design, Singer was able to combine the SPI-MV with a data logger and a 12VDC lithium battery to allow them to leave the probe unit in the vault for a month and acquire and save the flow data.  A USB is then used to extract the data off the data logger and the battery is recharged at the end of the month before the unit is then simply installed into one of the two additional vaults and the cycle repeated.  The installation is straight forward, once the SPI probe is removed the ball valve is closed allowing the valve to continue to run as normal and then the probe is moved to another vault and inserted into another pressure reducing valve.  As the unit only protrudes 8” from the valve and requires 12” for clearance, it fits easily in to all the chambers.

As the SPI-MV is accurate to 2% of reading throughout the specified velocity range, the utility is now able to confidently monitor the flow rates of their valves and compare loads to ensure equal flow.
