Angular circuit board assembly for a flowmeter

A flowmeter apparatus, comprising:

• a flowmeter comprising at least one sensor and a circuit board, wherein the at least one sensor is associated with a rotatable component, wherein the at least one sensor configured for at least one of mechanical detection of pulses associated to a rotary motion or electrical detection of the pulses associated to the rotary motion caused by the rotatable component;
• and
• an angular circuit board assembly that maintains the circuit board in an angular position with respect to the rotatable component associated with the at least one sensor in an arrangement that allows the rotatable component to dive through the circuit board, wherein the circuit board in the angular position maintains an angular gap with respect to the rotatable component, wherein the at least one sensor includes a flow channel and wherein the rotatable component oscillates to provide a measurement of a flow of fluid through the flow channel.

A method of operating a sensor apparatus, comprising:

• detecting pulses or a rotary motion with at least one sensor and a printed circuit board, wherein the at least one sensor is associated with a rotatable component and the printed circuit board is maintained by an angular circuit board assembly in an angular position with respect to the rotatable component associated with the at least one sensor in an arrangement in which the rotatable component dives through the printed circuit board and facilitates mechanical detection of pulses associated to the rotary motion or electrical detection of the pulses associated to the rotary motion by the at least one sensor, wherein the at least one sensor includes a flow channel and wherein the rotatable component oscillates to provide a measurement of a flow of fluid through the flow channel;
• and
• wherein the printed circuit board in the angular position maintains an angular gap with respect to the rotatable component.
