Abstract
The disclosed apparatus, systems and methods relate to a flow meter for flowable material configured to be used in non-vertical orientations.
Claims20
A non-vertical flow meter comprising:
- a) a chamber defining a lumen, the chamber disposed at a non-vertical flow angle;
- b) at least one pivoting sensing surface disposed within the lumen;
- and
- c) a load cell in operational communication with the at least one pivoting sensing surface,
- wherein the load cell is constructed and arranged to record the pressure of a flowing material applied to the at least one sensing surface.
2 more elements
A flow meter comprising:
- a) a flow measurement chamber comprising a lumen;
- b) a guide disposed within the lumen;
- c) one or more pivoting sensing surfaces disposed within the lumen;
- and
- d) a load cell in operational communication with the one or more pivoting sensing surfaces,
- wherein the entire flow measurement chamber is constructed and arranged to be disposed at a non-vertical orientation when in use, and
- wherein the load cell is constructed and arranged to generate an electrical output signal proportional to the pressure of a flowable material applied to the one or more pivoting sensing surfaces.
4 more elements
A flow meter comprising:
- a) a flow measurement chamber comprising a lumen having inlet and outlet ends;
- b) a guide fixedly disposed within the lumen configured to separate the flow of a flowable material into several streams;
- c) a plurality of sensing surfaces disposed within the lumen via a plurality of pivots and configured to be urged downstream by pressure applied to one or more of the plurality of sensing surfaces by the several streams;
- and
- d) a load cell in operational communication with the plurality of sensing surfaces and configured to measure material flow pressure via the several streams pressure applied to the sensing surfaces,
- wherein the flow meter is disposed such that the inlet and outlet ends of the lumen define a non-vertical axis for material flow.
