Single Chamber Orifice Fitting

Single chamber fittings are the most widely accepted means for gas measurement in the energy industry. 

The SureShot® Single Chamber is a rugged, field-proven unit that does the work you need it to do – easily, reliably, and safely.


SureShot® Single Chamber Orifice fittings fully conform to the latest AGA 3/API 14.3 stringent requirements.

They require no added uncertainty and provide accurate performance over the orifice plate beta ratio range from 0.1 to 0.75 within 0.5% flow accuracy to theoretical value..
