Page 6: System Recommendations
Page 6 System Recommendations Meter Selection The flow meter must be carefully chosen from the Meter Selection factors in the Engineering Manual. The meter must be selected based on the operating system and product characteristics. System variables include flow rate, temperature and pressure. -
Page 7: System Recommendations (Continued)
Page 7 System Recommendations (Continued) Thermal Shock The system operating temperature will expand or contract the metals within the flow meter. Systems that have sudden or immediate temperature increases of 68 F (20 C) degrees or more, will require clearance rotors. Clearance rotors will be necessary to eliminate the effect of immediate expansion of the rotors vs. -
Page 8: Start Up Recommendations
Page 8 Start up Recommendations WARNING Test equipment should be grounded to prevent a possible spark. Test area should have no ignition source. Operators should wear personal protection and prevent any product exposure and environmental issues. Start-up instruction for new installations or after maintenance and repairs: 1) Only properly trained personal should design, install, or operate metering system. -
Page 9: Direction Of Flow
Page 9 Direction of Flow The meter is set up at the factory for left to right flow. To change the meter to right to left flow, begin by removing the screws (#9 on the Meter Assembly Breakdown) and the adjuster cover plate (#7) on the front of the meter. -

Page 11: Meter Calibration
Page 11 Meter Calibration The method of proving should be selected, and necessary provisions made, during the design stage of the installation. Use only an accurate, specifically and scientifically designed prover. No other kind should be used. All provers should be checked periodically for accuracy. Weights and Measures officials have been very coopera- tive in giving assistance in checking provers. -
Page 12: Maintenance
SERIOUS INJURY OR DEATH FROM FIRE OR EXPLOSION COULD RESULT FROM MAINTE- NANCE OF AN IMPROPERLY DEPRESSURIZED AND EVACUATED SYSTEM. Total Control Systems flow meters and accessories are often used with LPG, petroleum, solvents, chemicals, and other liquids that may be explosive, extremely flammable, very toxic, oxidizing, and corrosive. Severe injury or fatalities may result if appropriate safety precautions are not followed. -
Page 13: Storage Instructions
Page 13 Maintenance WARNING Test equipment should be grounded to prevent a possible spark. Test area should have no ignition source. Operators should wear personal protection and prevent any product exposure and environmental issues. 10). When removing gaskets or o-rings, carefully check for damage or corrosion. Any cracked, rough, worn, elon- gated or swollen o-rings need to be replaced. -

Page 39: Meter Trouble Shooting
Page 39 Meter Trouble Shooting PROBLEM: Leaking packing gland and/or housing Two common causes of packing gland leakage are thermal expansion and hydraulic shock. If two valves in a pip- ing system (on either side of the meter) are closed at one time, and if the temperature rises as little as 1ºF in the system, it could result in a rise in pressure within the system that would exceed the working pressure rating of the meter. -

Page 40 Page 40 Vapor Eliminator Trouble Shooting PROBLEM: Product is flowing from the Vapor Eliminator vents A) Foreign matter located in between seal plate o-rings and metal reeds. B) The valve plate may be worn, requiring replacement. C) The float may have been punctured not allowing the float to rise and seal the air vents. D) The float may have been ruptured from a surge of pressure within the system. -
