METHOD AND DEVICE FOR MEASURING AIRFLOWS THROUGH HVAC GRILLES

A fan powered by a controlled external energy source and a flow measurement device measure the airflow exiting or entering grilles/registers of an HVAC system without impeding the airflow being measured. A flow straightening element is preferably employed to overcome any effects of a non-uniform or swirled airflow profile on the tan.

The RPM/flow calibration of the tan is insensitive to pressure differentials or the fan is a pressure-sensitive fan submitted to appropriate pressure differentials. Alternatively, the voltage or current supplied to the external energy source is used to determine the airflow. Finally, the pressure differential across the flow straightening element can be measured to determine airflow, eliminating the impact of pressure differential across the flow measurement device and fan.

Flow meter

A flow meter includes a housing which accommodates helical guide blades and a core located within the guide blades, and a measuring chamber in which a measuring ball can rotate in a circle.

Patent JPH0472174B2

Electric fluid flowmeter with photocell - comprises ball in tube rotating and oscillating with fluid flow

The flowmeter consists of a tubular conduit (10) mounted e.g. vertically with the fluid flowing downwardly through the conduit, a ball (12) disposed in the conduit, a stop (14) for supporting the ball, and a system for detecting oscillations of the ball. The conduit may be transparent with the detector system employing a light source for directing a light beam transversely through the conduit in the region of the ball and the light received by a photo-electric cell for the production of read-out signals. In operation, the ball rotates and oscillates from side to side in the conduit and thereby interrupting the light beam and producing pulse signals at a pulse rate dependent on the rate of fluid flow through the conduit.

Flowmeter for measuring low liquids flow rates - uses restricted inlet cross=section of body displacement annulus

The flowmeter, pref. for liquids, has an annular channel in a sealed housing. The liquid enters the channel via a tangential inlet (15), drives rounded bodies (17), pref. spheres, part a measurement point, and leaves via an outlet (16). The arrangement has an inlet of relatively narrow cross-section compared to the channel and outlet so as to produce more acceleration of the spherical bodies at the sensor (19) position and thus enable smaller flow rates to be measured than with conventional arrangements. The outlet (16) is also tangential to the channel (14). The specific wt. of the rounded bodies (17) is approximately equal to that of the liquid in the annular channel. The inlet is in the form of a nozzle whose cross-section is no more than half that of the outlet.

Fluid flow measuring sensor

Fluid flow meter

ABSTRACT This invention is a fluid flow meter with pulse output proportional to the fluid flow rate. The pulse is transduced by means of a pick-off sensor from the by-passing of a ball which travels in a toroidal passageway at speed close to that of the velocity of the fluid. The fluid flowing into the device follows a loop-shaped circular passageway while the ball travels in a closed circular passageway. Fluid flow propels the ball to revolve continu-ally at a rate directly proportional to the flow rate of the fluid.
