TO: Mayor Richard C. Irvin
FROM: David E. Schumacher, P.E.; Superintendent of Water Production
DATE: August 15, 2019
SUBJECT:
A Resolution Authorizing the Purchase of a replacement Insertion Magnetic Flowmeter for the Water Production Division.
PURPOSE:
To obtain City Council authorization for the purchase of an in-kind replacement insertion, magnetic flowmeter from Heartland Controls (Frankfort, IL) to upgrade/replace the existing flowmeter.
BACKGROUND:
The Water Production Division (WPD) utilizes various flowmeters at different locations within the city's water treatment plant (WTP). Flowmeters are common but necessary and essential equipment for measuring water flow at critical process points. Good process control requires accurate, instantaneous flow measurement for proper dosing of water treatment chemicals. Flowmeters also measure total flow at a given location over time, referred to as flow totalization.
DISCUSSION:
The subject flowmeter measures filtered water flow through the 48 inch filter effluent line at the WTP. The meter has been in service since 2002 and no longer provides the needed accuracy for this application.
The proposed replacement, a McCrometer Full-Profile Insertion (FPI) Magmeter, is a specialized product with technical features, design, and accuracy unlike other insertion style flowmeters. The WPD has previously purchased and installed the same model in the 42 inch filter effluent line and the well water bypass at the WTP, as well as two flowmeters at a remote booster station. The WPD seeks to maintain consistency with the McCrometer FPI model in this similar, filtered-water location.
Heartland Controls is the Exclusive Municipal Representative for the McCrometer FPI Magmeter in Illinois. Heartland Controls has provided a purchase quotation in the amount of $28,010.00, which includes installation and startup. As a comparison, the cost to purchase directly from McCrometer is $30,090.00 (additional cost for travel ...
