2. ULTRASONIC METER MAINTENANCE:

ONCE PER YEAR, VERIFY THAT WIRING CONNECTIONS ARE TIGHT.

EVERY 24-36 MONTHS, CHECK TRANSDUCER AND RTD SENSORS FOR TIGHTNESS AND CLEANLINESS.

ON-SITE CALIBRATION CAN BE PERFORMED EVERY 24-36 MONTHS AS DESCRIBED IN THE INSTALLATION AND MAINTENANCE MANUAL. ALTERNATIVELY, THE METER CAN BE SENT TO A CALIBRATION TESTING FACILITY.

3. ION 7550 RTU MAINTENANCE:

ONCE PER YEAR, VERIFY THAT CONNECTIONS ARE TIGHT.

BLOW DUST OUT OF PANEL AND WIPE DOWN.

NOTES:

1. METER COMPONENTS TO BE ORDERED AND INSTALLED WITH NO CABLE. CABLE LENGTH TO BE FIELD DETERMINED.

2. M-TMP TURBINE METERS:

- ROTOR MAINTENANCE SHOULD BE PERFORMED BY VISUAL INSPECTION EVERY 12 TO 14 MONTHS.

- ENSURE DEPTH SCALE HAS BEEN MARKED PRIOR TO REMOVING METER FOR INSPECTION.

- CAREFULLY REMOVE METER AFTER SECURING ISOLATION VALVE.

- CHECK THE ROTOR FOR BEARING DRAG OR SEIZURE. CHECK BY HOLDING THE ROTOR ASSEMBLY BETWEEN THE THUMB AND FOREFINGER, WHILE BLOWING ON THE ROTOR. IF THE BEARINGS ARE WORN, THE ROTOR MAY SEIZE OR SPIN POORLY.

- CHECK THE ROTOR FOR CONTAMINATION. LOOK FOR DEBRIS STICKING TO THE ROTOR BLADES. IF THE ROTOR STOPS SPINNING, THE BLADES MAY BECOME UNBALANCED. A CONTAMINATED BLADE WILL ALWAYS STOP OR UNBALANCE THE ROTOR. TO REMOVE HEAVY CONTAMINANTS FROM THE R

- ADDITIONAL MAINTENANCE INFORMATION CAN BE FOUND IN THE M-TMP METER INSTALLATION AND MAINTENANCE MANUAL.

- CALIBRATION SHOULD BE SCHEDULED EVERY 18 TO 24 MONTHS. THIS CAN BE DONE ON-SITE AS DESCRIBED IN THE M-TMP INSTALLATION AND MAINTENANCE MANUAL. ALTERNATIVELY, THE METER CAN BE SENT TO A CALIBRATION TESTING FACILITY.

3. LIMITED INFORMATION AVAILABLE. FLOW RATES ARE ESTIMATED BASED ON PIPE SIZE.

- CHECK THE ROTOR FOR BENT BLADES OR BENT YOKE. ALL TURBINE BLADES ARE PROFILED FOR DIFFERENT FLOW CONDITIONS. LOOK FOR THE BLADE(S) WHICH VARY FROM THE FACTORY PROFILED BLADES. THE YOKE, WHICH HOUSES THE TURBINE, IS USUALLY DAMAGED WHEN THE GATE V
