Tek-DP 1610A Single Chamber Orifice Fittings are the single chamber devices designed for precise flow measurement in oil and gas applications with a simple plate removal technique. These fittings are suitable for liquid flow measurement as well. Tek-Trol ensures that each single chamber fitting undergoes rigorous testing under pressure conditions to provide maximum safety to the user and the system.

The single chamber fittings are manufactured in accordance with ANSI, AGA/API, and ASTM standards for pressure tap integrity, positive plate seal, seal protrusion, and eccentricity. These single chamber orifice fittings can be installed in vertical or  horizontal lines and are available in a wide range of pipe sizes from 2″ to 48″. These fittings allow ease of orifice plate replacement or inspection in a depressurized flow line without physically removing the meter from the line.

The Tek-DP 1610A Single Chamber Orifice Fittings are best used in the applications where replacing the orifice plate under pressure conditions is risky and a nominal shutdown time is acceptable. The plate removal procedure does not require removal of the flange bolts or spreading of flanges. This prevents potential leakage of process fluid and safeguards the operators.
