Abstract: A technique for determining a boiler water condition includes a boiler controller (aka PSE unit) having a signal processor that implements a boiler control algorithm to receive signaling containing information about sets of N consecutive probe data samples related to a boiler water condition; determine stable average signaling containing information about a stable average by averaging a set of N consecutive probe data samples in the signaling received; determine present stable average signaling containing information about a present stable average by averaging a present set of N consecutive probe data samples in the signaling received; and determine corresponding signaling containing information about the boiler water condition, based upon whether the present stable average is within an allowable limit and a comparison of the present and previous stable average signaling determined.

Abstract: A flow switch assembly features a two-part base assembly having lower and upper base parts. The lower base part is made from a metallic material, adapted on piping having a fluid flow, and configured with a central orifice to receive a paddle arm that pivots on an axis and responds to fluid flow in the piping. The upper base part is made from a non-metallic material, configured with a corresponding central orifice to receive the paddle arm, and configured with a channel to receive a pivot arm to mount and allow the paddle arm to pivot on the axis to actuate an ON/OFF switch in response to fluid flow. The non-metallic material has a lower coefficient of heat transfer than the metallic material to reduce condensation build-up in the flow switch assembly when the flow switch assembly is used in cold applications and exposed to temperatures below freezing.

Abstract: A valve includes a body having upstream and downstream ports to measure upstream and downstream pressures and configured on a common axis, and a ball arranged in the body to rotate re the common axis between open and closed positions to allow for fluid flow and no fluid flow. The ball has a calibrated member having a calibrated orifice to allow fluid flow and has a flow coefficient and upstream and downstream pressure taps located upstream and downstream of the calibrated orifice and in fluidic communication with the upstream and downstream ports to measure upstream and downstream pressures when in the open position and angled re the common axis, so a direct flow measurement of fluid flow is determined based on a measured pressure differential between upstream and downstream pressure taps re the flow coefficient of the calibrated orifice when in the open position.
