Residential Diaphragm Gas Meter

 Using Gas   City Gas L.P.G  L.N.G. Anti-corrosive Gas      Features   G-series : DAESUNG GAS METER is produced according to the recommendation of O.I.M.L. --Standard. Durability : The newest engineering plastics ensures its persistence. Rotary riveting : Use of the riveting methods for connecting distribution lever with a connecting --rod.  G-Series has function of measuring minute flowrate and indicates the stable measuring typical--accuracy curve in a range of minimum through maximum flowrate .  Option : Remote Reading Gas Meter.      Installing Place   Install the Gas Meter at well-ventilated place where is easily read and serviced. Clean place which is maintained over 60? from the electric machines. Place to be kept out of vibration and direct ray. Place to be apart from humidity, fire, corrosive gas and chemicals.      Caution   Do not give a impulse or forcible power to the unit. Before installing the Meter, all obstacles such as oil and dust must be purged from the meter--and connected pipework. Install the meter at level. Install the meter for gas enable to be flowed following arrow(?).      Checking points after installing   Paint all gas tight parts including connecting pipe, gas meter and others with soap-suds. Ignite the gas equipment after gas passes through and then check the Index in the meter.      Metrology   DSG gas meters satisfy O.I.M.L. and E.E.C. specifications as well as K.S. according to these--metrological standards.  Prior to inspection of the certified authority, gas meters are tested at Qmin, 2Qmin, 0.2Q max --and Qmax and flow testing by Bell Prover, standard tester.      Working Principle  G-Series are designed to a solid chamber.  Gas passing through the chambers of inlet and distribution. Rubber diaphragm's moving in right and left-transfer the rotary motion of blade shaft into the --reciprocating motion of the distribution lever and connecting rod. With right and left moving of the diaphragm, the blade point connected to diaphragm makes a--rotary motion to the crankshaft. The rotary motion transmitted by shaft-gear 10, makes indicate the gas flow rates up to --maximum 99999? in decimal system, by operation of control gear and counter gear.  the new residential safety gas meter, to which enable the remote reading meter to be --connected, the function of SP50-safety intelligent valve.
