A flow sensing device includes 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.

Fluid monitoring module arrangements

A fluid heater includes a heating circuit, a temperature monitoring circuit, a controller, and an overheat sensing element. The controller is disposed in a control unit and is in circuit communication with a temperature gauge and a power supply switch, the controller being configured to operate the power supply switch in response to feedback from the temperature gauge to maintain the heater at a setpoint temperature. The overheat sensing element is disposed in a heater housing proximate to a thermal fuse and is in circuit communication with the controller to provide an indication to the controller when the overheat sensing element reaches an overheat temperature lower than the critical temperature. The controller is configured to operate the power supply switch to reduce or shut off power to the heating element in response to receiving the indication that the overheat sensing element has reached the overheat temperature.

Electrical heater for flow control device

A fluid monitoring module includes a flow sensing device and a controller disposed in an enclosure. The flow sensing device includes a body including an inlet port, an outlet port, an upstream sensor port, a downstream sensor port, and a flow passage disposed between the inlet port and the outlet port, and between the upstream sensor port and the downstream sensor port. A first fluid sensor is assembled with the upstream sensor port, and a second fluid sensor is assembled with the downstream sensor port. The controller is in circuit communication with the first and second fluid sensors for receiving at least one of pressure indicating signals and temperature indicating signals from each of the first and second fluid sensors, and for measuring fluid data based on the received signals.

A fluid component includes a cross-shaped body having laterally extending first and second flow ports and axially extending first and second access ports. The first flow port connected in fluid communication with the first access port by a first branch port. The second flow port connected in fluid communication with the second access port by a second branch port. The first and second access ports are connected in fluid communication by a convoluted flow restricting passage extending generally axially from the first access port to the second access port.

Laminar flow element

A fitting for a fluid conduit includes a coupling body, a coupling nut, a conduit gripping device that is axially driven by the coupling body and the coupling nut to provide grip and seal against a conduit, and a strain sensor unit disposed on a neck portion of the coupling body, the strain sensor unit including at least a first axially extending strain sensor positioned and oriented for strain sensor unit measurement of a first strain of the neck portion corresponding with a first fitting assembly condition, and a second strain of the neck portion corresponding with a second fitting assembly condition different from the first fitting assembly condition.

System and methods for strain detection in a coupling

A fluid sample system includes a control system that operates in the hazardous area and controls one or more valves and optionally receives outputs from one or more transducers and optionally one or more sensors. The fluid sample system includes components that operate in a hazardous area and includes a control system that operates in the hazardous area and that controls one or more electrical devices. The control system communicates across a barrier with a system on a safe side of the barrier with as few as two intrinsically safe couplings including a single pneumatic coupling and a communication link coupling. The control system includes an intrinsically safe voltage boost circuit.
