1. A flow sensing device comprising:
a first body member defining an inlet port, an upstream sensor port, and a first connecting port;
a second body member defining an outlet port, a downstream sensor port, and a second connecting port;
a flow restricting element defining a flow restricting passage and including a first end connection coupled to the first connecting port and a second end connection coupled to the second connecting port, such that the flow restricting passage is disposed between the inlet port and the outlet port, and between the upstream sensor port and the downstream sensor port;
a first fluid sensor assembled with the upstream sensor port; and
a second fluid sensor assembled with the downstream sensor port;
wherein the first and second end connections comprise zero clearance connectors that provide for removal and reinstallation of the flow restricting element with the first and second body members without movement of the first and second connecting ports, the zero clearance connectors each including a male threaded connector having an end face groove retaining an O-ring seal.
