GHG & Surface Casing Vent Measurement

The Hawk Vent Gas Meter is designed to measure and digitally log low flow vent gas, such as methane, with high accuracy. Typical applications are surface casing vent, compressor seals, pneumatic control gas usage, and any vent gas where high accuracy measurement and audit trails are required. This is no lab grade toy. It is designed to be used unattended in the field where vent gas is not always clean and field conditions can be muddy.

Light weight, portable, hazardous location approved, designed and built in Canada for Canadian conditions. The Hawk is trusted by Industry, Governments and Academia across North America to provide accurate logged vent flow field data.
