Honeywell TRZ2 Turbine Flow Meters

The Honeywell Elster turbine meter TRZ2 is for fiscal and non-fiscal applications of measuring natural gas. The gas meter is a custody-transfer approved by PTB and NMI.

Turbine Meters

The Honeywell Elster turbine gas meters are accurate and reliable for measuring the gas in gas distribution and transmission, industrial plants, and business operations. The Elster TRZ2 is available in sizes 2-6 inches and pressure classes up to ANSI 600. For sizes above 6,” Honeywell offers the SM-RI-X turbine meter which is available up to 24″.

Features & Benefits

Features and Benefits

The patented Honeywell Elster metering cartridge permits repeatable measurement even under imperfect inlet flow conditions. Additionally, having the cartridge can significantly reduce service time in the field. Due to its design, ambient temperature changes have minimal effect on the meter's performance as the cartridge is separate from the meter body.
