Abstract

The flow, pressure, pulse rate, conductivity and/or light transmission characteristics of a fluid are measured in-line with the fluid passage, in a manner which minimizes impedance to the flow in the passage.

Fluid Path In/Line Detection of Flow, Pressure, Conductivity and/or Opacity

The flow, pressure, pulse rate, conductivity and/or light transmission characteristics of a fluid are measured in-line with the fluid passage, in a manner which minimizes impedance to the flow in the passage.

Flow path tubing 10 is fabricated from clear molded materials capable of passing light. Vertical column 11 is surrounded by an opaque base 12 which contains a series of apertures on each side, such as 13 and 14. Light sources such as 15 are arrayed to focus through appropriate ports 13 and 14 into respective receivers such as 16.

An opaque ball 17 is in-line with the main fluid flow passage 18 and forced upward, and thus into the path between the light sources 15 and receivers 16 as a function of the pressure in passage 18 from fluid flow. The outputs of the light receivers 16 can be monitored by a computer input to detect ball peak elevation, minimum elevation, and the frequency of oscillation of ball 17.

Conductivity probes 20 and 21 allow measurement of the electrical conductivity of the fluid inside passage 18. The light source 25 and light receiver 26 across the fluid flow passage 18 permit determination of the degree of clarity or opaqueness of the fluid in passage 18. A housing sleeve 27 retains light source and receiver 25 and 26 in isolation from external light sources. Fig. 2 is essentially a sectional-view taken along line A - A of Fig. 1.
