9. Sensing of meter failure shall activate a user configurable zero or 100% output signal and a failure alarm contact closure.

10. Provide automatic empty pipe detection.

11. Include non-volatile memory so that flow totals and calibration are not lost during a power outage.

E. Manufacturers:

1. Siemens FM MAG 5100W or Endress + Hauser Promag W 400 or approved equal.

NOTES AND GENERAL INFORMATION

3. Stratigraphic Contacts: Solid line denotes a sudden, observed soil transition.

Dashed line denotes a gradual or gradational soil transition.

Dotted line denotes an inferred transition, therefore the type and specific location of the transition is unknown / approximated.

3. Common abbreviations: WOH = Weight of (SPT) Hammer DHH = Down Hole Hammer HA = Hand Auger DR = Drove Rock (During SPT) NR = No Recovery Ppen = Pocket Penetrometer (unconfined compressive strength in tons per square foot)

1. Drilling and sampling activities are indicative of subsurface conditions only at locations where data are taken, and when data are taken. Conditions at locations not evaluated may differ from professional interpretation.

2. Environmental boring logs present soil and groundwater data collected for resource development, depositional environment, groundwater flow and/or contaminant transport analyses and may not for be suited for geotechnical or structural engineering use unless otherwise arranged.
