G004HZ Gear Flow Meter

Robust resolution in a compact package allows you to measure precisely and accurately even in the worst environmental conditions. Max HZ Gear Meters are built out of 316 stainless steel for increased corrosion resistance in the exposed environments of the oil and gas industry and other process industries.

Choose from frequency or analog transmitter options. High temperature models up to 130°C available. Only available as CE Certified, Ex-proof version with ATEX/IECEx and UL/cUL certifications.
