Work order for calibration and reinstallation of eleven pressure
transducers for the Fort Collins Flood Warning System
DIAD Incorporated (DIAD) will complete the following activities as a fixed price work order under
our existing contract with the City of Fort Collins (City)
DIAD will calibrate and reinstall the following pressure transducers (PT)
1 Poudre River at canyon mouth
2 Dry Creek at Shields
3 Boxelder at Cnty Rd 56
4 Fossil Creek at College
5 Fossil Creek at RR tracks
6 New Mercer at Harmony Rd
7 Avery Park - Detention pond and Irrigation canal (this site has two PTs)
8 Spring Creek at BNRR
9 New Mercer at Rolland Moore
10 Larimer #2 at Rolland Moore
DIAD will calibrate each PT by applying a series of known pressures and recording the voltage
response of the PT A linear equation will be fit to the series of test points The tests and the
resulting linear equation will be generated using the Maintenance Tracker (MT) Software and the
current MT database for the City The resulting coefficients from the linear equation for each PT
will become the new calibration parameters to be entered into the STORM Watch base station
software maintained by the City
After calibrating each PT, DIAD will reinstall the PT to its final monitoring location at each site
The PTs will be installed so that they rest on the bottom of either the stilling well or riser pipe
DIAD will document all calibration and reinstallation work using the Maintenance Tracker
software A copy of this database will be made available to the City DIAD will submit hardcopy
reports summarizing the work completed The hardcopy reports will include the new calibration
coefficients The City from either the hardcopy reports or the MT database can update the
STORM Watch base stations
DIAD will perform the work sometime between March 7 and March 14, 2001 We will coordinate
all activities with the City
