Abstract:
1. An apparatus for the control and measurement of the flow of gas, comprising: a) A rotary control valve; b) A planar base plate having a plurality of cavities to accept the different components of the apparatus; c) A direct current reversible non-sparking electronically commutated electric motor, said electric motor having gears to turn said rotary control valve; d) A position sensor to determine the position of said rotary control valve; e) A gas pressure sensor for measuring the gas flowing pressure and for the redundant check of the seating of said rotary control valve in fully closed position; f) An electric commutation switching and control circuit for said electric motor, wherein said control circuit turns electric motor on and off and reverses the rotary control valve's rotation direction; g) A remote supervisory device; h) digital communications means for receiving external commands for opening and closing of said rotary control valve in response to an emergency or administrative action from the remote supervisory device; i) An embedded microprocessor based gas metering apparatus for the measurement of gas flow at standard conditions; j) An electric energy generating and storage system for the operation of the apparatus.
