The Roto-Boss is designed to give you five different orifice plate selections which are changeable for measuring gas, instead of the single orifice plate in most traditional meter fittings. Our system allows the operator to simply rotate the plate to utilize a different sized plate - a 10 second change - without interrupting the gas flow.

The basic Roto-Boss consists of two concentric companion flanges, a center plate assembly, the multi port orifice plate and five orifices. A rotation shaft is rotated from outside the flange to change and align the orifice plates with the inlet and outlet pipe openings. Gas passing through the pipe also passes through the orifice plate centered in the pipe.

Significant savings occur when the 'down time' is removed. Plate selection can be accomplished without ever shutting down the line. Less handling of the orifice plates results in less damage.

This design is even more valuable from a safety point of view. The Roto-Boss enables the end user to change plates without any exposure to potentially harmful gases (sour) or pressures. When the need to open up the orifice changer to change plates is eliminated, operator safety is drastically increased.

The Roto Boss future design is looking to accommodate remote monitoring and computerized plate changes through the SCADA System. With the aid of actuators and positioners, the Roto-Boss can change plates automatically for remote and automated sites.

The Roto Boss delivers consistent and accurate metering, safety and savings, without the downtime.
