A connection terminal is on a flange of a thermal flow meter. A terminal connection part has a first and a second bent part. The first bent part is bent from a first direction to a second direction. The second bent part has is bent from the first bent part to a third direction. The first and second bent parts are formed such that when connection pin parts of a plurality of the connection terminals and terminal connection parts of the plurality of connection terminals are projected onto a first imaginary plane, an imaginary line L extending along a first direction passing through the projection areas of each of the terminal connection parts of the plurality of connection terminals passes between the projection areas of the connection pin parts from among the connection pin parts of the plurality of connection terminals, that are positioned on both sides.

A fluid injector system includes at least one injector for pressurizing and delivering at least one fluid from at least one fluid reservoir, at least one fluid path section in fluid communication with the at least one injector and having a predetermined index of refraction, and a first proximal sensor and a first distal sensor arranged along the at least one fluid path section. Each of the first proximal sensor and the first distal sensor includes an emitter configured to emit light through the at least one fluid path section, and a detector configured to receive the light emitted through the at least one fluid path section and generate an electrical signal based on the received light. The fluid injector system further includes at least one processor programmed or configured to determine, based on a difference in the electrical signals generated by the first proximal sensor and the first distal sensor, at least one property of a content of the at least one fluid path section.

An apparatus and method for determining fluid flow (e.g., sterile media flow, filtrate flow, etc.) through tubing is provided. The apparatus includes an air source, a flow valve, a first sensor, a second sensor, and a media tubing section extending between the first sensor and the second sensor. In operation, air from the air source is introduced by the flow valve into a fluid flow to create a lead line of fluid immediately following the introduced air. As the lead line of fluid passes each sensor, the sensors are used to determine a time between when the lead line passes the first sensor and the second sensor and that determined elapsed time is used, along with a determined volume of the media tubing section to determine the rate of flow of the fluid flow.
