Pay-Check

Elster-Instromet is a manufacturer of both turbine and ultrasonic meters, and we are proud to offer even better metering technology by combine these in a serial solution. This approach has several advantages:

  • further reduction of measurement uncertainty
  • significant decrease of financial risk 
  • ideal to analyze major flows


A well-proved method is the online comparison or Pay-Check configuration. This means that two meters are continuously in series: one meter is used for the billing of used gas, while the other meter verifies the pay meter.
