Safety Procedures NOTICE This manual provides warnings and procedures that are intended to inform the owner and/or operator of the hazards present when using the Liquid Controls Meter on LPGas and other products. The reading of these warnings and the avoidance of such hazards is strictly in the hands of the owner-operators of the equipment. Neglect of that responsibility is not within the control of the manufacturer of the meter.
Safety Procedures Safely Evacuate Be Prepared Piping System ! WARNING Before disassembly of any meter or accessory component: ALL INTERNAL PRESSURES MUST BE RELIEVED AND ALL LIQUID DRAINED FROM THE SYSTEM IN ACCORDANCE WITH ALL APPLICABLE PROCEDURES. -Pressure must be 0 (zero) psi. -Close all liquid and vapor lines between the meter and liquid source. For Safety Rules Regarding LPG, refer to NFPA Pamphlet 58 and local authorities.
Introduction Principles of Design Liquid Controls mechanical air and vapor eliminators remove air and vapor from metering systems. Removing the air and vapor from a metering system increases the accuracy of the meter by allowing only liquid to pass through the meter for measurement. At installation, LC mechanical air and vapor eliminators are piped to a storage tank to provide a pathway and a receptacle where the evacuated air and vapor can be deposited.
Introduction Principles of Design Air Check and Differential Valves Air check and differential valves are spring loaded valves on the outlet side of the meter. Most Liquid Controls meter systems with an air eliminator also have an air check or a differential valve. Air eliminators and air check (or differential) valves work in conjunction to stop the flow of product through the meter until the air is eliminated from the system.
Introduction Principles of Design Dual Head Bulk Plant Air Eliminators By employing two air eliminators, a high mount air eliminator and a low mount air eliminator, dual head bulk plant air eliminators save the metering system from shocks incurred by recurring small slugs of air (or vapor) and prevent large slugs of air from passing by the air eliminator and through the meter system. Each time a standard air eliminator removes a small slug of air, it closes the downstream differential valve.

Field Piping ! WARNING Relieving Internal Pressure All internal pressure must be relieved to zero pressure before disassembly or inspection of the strainer, vapor eliminator, any valves in the system, the packing gland, and the front or rear covers. Serious injury or death from fire or explosion could result in performing maintenance on an improperly depressurized and evacuated system. Relieving Internal Pressure Procedure for LPG and NH3 Meters 1. Close the belly valve of the supply tank. 2.
Field Piping Piping Configurations & Connections Piping configurations for Liquid Controls mechanical air and vapor eliminators are determined by two factors, the presence or absence of a valve in the meter system and the presence or absence of bypass ports and a limited bleed valve plate in the mechanical air eliminator assembly. If the meter system has an air check or differential valve, the air or vapor eliminator and the valve must be piped together.
Field Piping Piping Guidelines • Pipe with as little restriction as possible. By minimizing restrictions, the air or vapor eliminator will work as efficiently as possible. • ¾" (or larger) pipe/hose is recommend to vent air or vapor to the storage tank. • ½" pipe/hose is recommended for piping to an air check or differential valve (⅜" is acceptable). • If using hose, choose a type that will not collapse in on itself (heater hose, hydraulic hose, etc.).
Maintenance ! WARNING Relieving Internal Pressure All internal pressure must be relieved to zero pressure before disassembly or inspection of the strainer, vapor eliminator, any valves in the system, the packing gland, and the front or rear covers. Serious injury or death from fire or explosion could result in performing maintenance on an improperly depressurized and evacuated system. Relieving Internal Pressure Procedure for LPG and NH3 Meters 1. Close the belly valve of the supply tank. 2.
Maintenance To Replace the Reed Strips & Float Assemblies 1. Remove the 4 screws and washers at the base of the air eliminator. Pull the air eliminator off the strainer. 2. Remove the baffle plate and the baffle cup (aluminum air eliminators only) from the housing. If the air eliminator has a lock nut and a bushing on the bottom of the guide post, remove them. 3.
