Manual Addendum 1010FMA-4

SETUP PROCEDURE FOR “WET-FLOW CALIBRATED” 1010 SYSTEM

Caution: DO NOT use the field manual installation procedure to startup a wet-flow calibrated system. Doing so could void the calibration by corrupting es- sential data. This addendum contains the only authorized instructions to be used when commissioning a wet-flow calibrated 1010 system.

1.INTRODUCTION

When the system 1010 is wet-flow calibrated, the flow computer stores the installation param- eters in its storage memory. Each flow calibration is assigned a unique site name. Usually, the site name corresponds to the pipe size. For example, a 3-inch carbon steel, schedule 40 pipe would be given the name “3CS40.”

The flow calibration report issued with each wet-flow calibration, includes a flow calibration “Diagnostic Data Sheet.” This data sheet lists the site name and other necessary information (such as transducer serial number and spacing information), for setting-up the flowmeter. A wet-flow calibration applies to a specific flowmeter and set of transducers; identified by serial numbers on the diagnostic data sheet.

NOTE: In order for the flow calibration to be valid, the flow computer and transducers being used must have the same serial numbers as those listed for the site on the Calibration Diagnostic Data Sheet.

2.SETUP PROCEDURE

2.1Transducer Installation

2.1.1Refer to the diagnostic data sheet to find the mounting mode (Direct or Reflect) used during the wet-flow calibration. Review the transducer installation guidelines in your 1010 field manual.

2.1.2Refer to the diagnostic data sheet for the transducer spacing index utilized during the flow calibration. Using the mounting configuration employed during the flow calibration, install the transducers on the pipe at the above noted spacing positions in accordance with the instructions provided on the transducer installation drawings.

2.1.3Attach the transducer cables noting that the cable marked “UP” attaches to the trans- ducer closest to the source of flow.

NOTE: Before proceeding further, ensure that the pipe is full of liquid. It is not impor- tant at this point that it be flowing.
