About this file
This document contains a request for information and responses regarding a federal contract opportunity to add chilled water metering at the Louis Stokes Cleveland VA Medical Center. The solicitation requests dimensional details and straight run lengths for existing chilled water supply and return pipes servicing seven air handling units to properly specify ultrasonic flow meters as an equivalent replacement for discontinued Flexim ADM 7407 models. Responses provide the requested pipe diameter, run length, and flow meter location information for each air handling unit, noting that dimensions should be verified in the field. The closing date for questions on Opportunity Number Y1DA remains May 19, 2021, with all other terms and conditions unchanged.

INFORMATION NEEDED:
Specification 23 09 23 Part 2.8 Sensors (Air, Water and Steam) section C. specifies Flexim ADM 7407 ultrasonic clamp on meters or equivalent. We are planning to offer the Flexim Model 721 since the ADM 7407 has been discontinued and is obsolete. The Flexim Model 721 exceeds the design parameters of the ADM 7407.
Since we were not able to view all project AHU’s can we please have the following information to properly specify related equipment and insulation?
1. Drawing M-602, Configuration C Diagram. Can we please have the CHW supply pipe (A-05) diameter, CHW return pipe (A-07) diameter and approximate length of straight pipe for desired flow meter location on the CHW supply pipe (A-05)?
2. Drawing M-605, Configuration J Diagram. Can we please have the CHW supply pipe (A-09) diameter, CHW return pipe (A-11) diameter and approximate length of straight pipe for desired flow meter location on the CHW supply pipe (A-09)?
3. Drawing M-606, Configuration L Diagram. Can we please have the CHW supply pipe (A-15) diameter, CHW return pipe (A-13) diameter and approximate length of straight pipe for desired flow meter location on the CHW supply pipe (A-15)?
4. Drawing M-607, Configuration M Diagram. Can we please have the CHW supply pipe (A-13) diameter, CHW return pipe (A-15) diameter and approximate length of straight pipe for desired flow meter location on the CHW supply pipe (A-13)?
5. Drawing M-609, Configuration Q Diagram. Can we please have the CHW supply pipe (A-19) diameter, CHW return pipe (A-17) diameter and approximate length of straight pipe for desired flow meter location on the CHW supply pipe (A-19)?
6. Drawing M-609, Configuration R Diagram. Can we please have the CHW supply pipe (A-15) diameter, CHW return pipe (A-13) diameter and approximate length of straight pipe for desired flow meter location on the CHW supply pipe (A-15)?
7. Drawing M-610, Configuration T Diagram. Can we please have the CHW supply pipe (A-04) diameter, CHW return pipe (A-06) diameter and approximate length of straight pipe for desired flow meter location on the CHW supply pipe (A-04)?
