PULSE GAS METER: (PG1, PG1.6, PG1 (A-I), PG1.6 (A-I), PG1.6 (S), PG2.5 (S), PG4 (S), PG1.6 (A), PG2.5 (A), PG4 (A))
PG series gas meter are the new generation products, which are developed for market requirement. This series gas meters have the functions to transform the flow rate revolutions to be the pulse signals. Through micro power magnification and plastic recovery, the pulse signal can be transmitted to remote places, which have the features of remote transmission without any electric consume and any contact points, 4000 Gauss anti-magnet interference and steady signal source.
They are especially suitable for the required remote automatic reading system with higher performance.
General speaking the pulse signal can be acquired from some ways of the reed relay or Hall element and digital remote counter, etc. Among them the reed relay pulse signal generators, which are installed a magnet steel in the first decimal drum of the counter and each reed relay on the upper and lower of the counter frame respectively, will send a pulse signal after one revolution which is just equal to 10 liters gas through gas meters.
