Compact electronic volume converter ELCORplus

he latest Elgas technology ELCORplus and ELCOR represent powerfull solution applicable either like electronic volume corrector for billing purposes or like universal datalogger for station control and monitoring. Both models are designed as compact devices integrating measuring metrological part together with communication unit and with telemetry features as well. The most powerfull model is . Its robust design together with tremendous modularity covers all known demands of gas segment over EVC ( ELCORplus) and datalogger installation ( DATCOMplus). Battery powered ELCORplus converts gas volume under operating conditions to gas volume at base conditions, according to state equation. Information about primary volume can be received from all types of gasmeters through LF pulses (reed contact or wiegand sensor), HF pulses and absolute encoders (NAMUR, SCR+). The meter can be connected through mechanical index with Elgas relative encoder. EVC calculates the conversion factor C based on actual value of gas pressure, gas temperature and based on compressibility factor according to all known methods. The basic concept enables to use device either as a single or dual channel EVC with possibility to add nonmetrological channel. Modular architecture enables to create various configurations up to 6 pressure or temperature transducers, 12 digital inputs, 4 digital outputs, 6 analogue inputs and 4 analogue outputs, based on customer requirements. Any configuration can be individually customised by parameter file locally or remotely.
