Coriolis flow meters in natural gas have been accurate and pretty inexpensive since the 1990s with accuracies better than 99% on the extreme low end and 99.5% on the high end.

Its easy to say that anything is 'too expensive' when the regulatory bar is set so low that it doesn't exist.

Right, you could put a combustible-gas-safe mass flow sensor on every gas line, high and low pressure, at a cost of roughly 100x current rotary and aperture flow meters, but then metering would become by far the largest cost in gas production.

Nope, Ex rated coriolis flowmeters are barely $150k.

A residential rotary gas meter costs less than €15, and that's the long tail you need to replace to measure losses accurately.

Edit: And current turbine and aperture flow meters cost hundreds.

Ok...I don't think everyone here is saying you should put a Coriolis meter on every single residential service. That would be insane.

> Even if not every pope is metered, at the very least there should be metering at the point of bulk purchase (eg. from a LNG ship) to the end user (gas meter at a home).
