| A digital rain gauge which collects rainwater and then internally discharges the collected water in the form of individual droplets of equal volume. The discharge of each droplet is then detected and transmitted to a signal processor, which, in turn computes the amount of rainfall accumulated based upon the drop discharge rate and the determined drop volume. | ||||||

| A gas flow measuring device comprising a flowtube, a soap bubble generator for generating a film of soap, a manually adjustable member for controlling the transfer of the soap film to the flowtube and a set of detectors spaced apart along the flowtube for measuring the time displacement of the soap bubble between the spaced positions of the detectors. The manually adjustable member is preferably a hoop surrounding the flowtube. A soap bubble is formed by immersing the hoop into the soap solution and withdrawing it. A soap film is transferred to the flowtube by raising the hoop to the mouth of the flowtube. In a second embodiment, a sleeve with slots surrounds a flowtube with slots. The sleeve is rotated into alignment with the flowtube to transfer a soap film. | ||||||

| A device for measuring the volume of flow in a liquid conveying apparatus wherein the length and velocity of a liquid column are measured. Drops of the liquid are formed and directed into a length of measurement tubing having a known internal diameter. As the liquid column is passed through the measurement tubing its length is determined by two spaced apart liquid sensors. The actual length is determined by calculating the time elapsed for the leading edge of the liquid column to interrupt the two liquid sensors. The time for the trailing edge to pass the first sensor is proportioned to the length of the column and the quotient of the two values will give the actual length. Accordingly, accurate volume determinations can be made irrespective of velocity change such as due to viscosity, surface tension or back pressure. The device of this invention is especially adapted to be used in conjunction with an intravenous administration set. | ||||||
| 84 | Self-compensating optical drop count apparatus for measuring volumetric fluid flow | US083002 | 1979-10-09 | US4314484A | 1982-02-09 | Robert J. Bowman |
| A self-compensating optical drop count apparatus for measuring volumetric fluid flow by optically counting the number of drops of fluid that pass through a drop chamber, each drop being formed so as to be of approximate equal volume. Optical counting circuitry is designed to count each drop only once. The count is accumulated in a holding register where it may interface with external instrumentation equipment adapted to display the count and/or convert it to a volumetric measurement by multiplying it by the average volume of fluid contained in each drop. A compensation technique is utilized to maintain the intensity of a light beam, through which the drops must pass, at a constant level. Compensation is achieved in a closed loop system which varies the drive current to the light emitter to compensate for long-term variations that occur in the intensity of the light beam as sensed at a light detector. Compensation techniques are also utilized in converting the count to a volumetric measurement to account for known changes in drop volume as a function of drop rate. | ||||||

| 98 | Method and apparatus for measuring mass of milk slag and value corresponding to milk flow rate thereto | JP11949992 | 1992-03-27 | JPH0658789A | 1994-03-04 | TEIRUMAN HOEFUERUMAIERU; YAKOBU MAIERU YUN |
| PURPOSE: To accurately measure the mass of milk slag and flow rate of milk by detecting the length of milk slag in a tube inside at an interval from the inner wall of a milk hose tube. CONSTITUTION: Milk slag 1 in a milk hose 2 is urged along feeding direction D, the end 3 is bulged, and a cavity is formed at the rear end 4. The cavity is increased during feeding to become cavities 6, 7. Accordingly, the slag having the same length La measured from the exterior might have considerably different quality. Thus, the interval Li between the two lines 11, 11' and 12, 12' extended at a distance d/4 (d is the inner diameter of the tube) from the inner wall 5 and the intersection of the profiles at the front and rear ends of the slag 1 is decided as the length of the slag 1. The product of the length and the sectional area of the hose 2 becomes the value allowable as the real mass of the slag. Accordingly, the length of the slag is measured by detecting the slag passing between the measuring points on the lines 11, 12. | ||||||
