Abstract

A flowmeter for liquids has a measuring housing, which encloses and rotatably mounts an impeller, said measuring housing comprising a one-piece supply pipe and discharge pipe, wherein the impeller is eccentrically arranged in the discharge pipe after a nozzle-forming constriction. A sensor encoder is associated with the impeller and a sensor which responds to the sensor encoder is provided on the measuring housing for determining the amount of liquid flowing through the measuring housing on the basis of the revolutions of the impeller. The outer diameter corresponding to the impeller is smaller than the nominal inner diameter of the discharge pipe, enabling it to be pushed into the one-piece pipe.

Abstract

A flowmeter for liquids has a measuring housing (10), which encloses and rotatably mounts an impeller (50), said measuring housing comprising a one-piece supply pipe (12) and discharge pipe (13), wherein the impeller is eccentrically arranged in the discharge pipe (13) after a nozzle-forming constriction (14). A sensor encoder is associated with the impeller and a sensor (90) which responds to the sensor encoder is provided on the measuring housing (10) for determining the amount of liquid flowing through the measuring housing (10) on the basis of the revolutions of the impeller. The outer diameter corresponding to the impeller is smaller than the nominal inner diameter of the discharge pipe (13), enabling it to be pushed into the one-piece pipe (12, 13).

Abstract

In order to determine the through put of a fluid flow in a pipe with a minimum of technical and particularly equipment expense, the invention proposes a method and a device for determining the throughput of a fluid flow, wherein the method provides for the fluid to be heated by means of an optical heating beam and for the heating site to be irradiated by an optical detection beam, wherein the optical axes of the heating and detection beams correspond at least at the heating site, and the detection beam is recorded by a detector array; and the device is designed such that the unit for heating an inner region of an adjacent inner region of the fluid and an optical arrangement guiding the beam of the laser are disposed such that a measurement beam passes through the heated region at the absolute location of the heating thereof.

Abstract

The present invention relates to a plastic ultrasonic measurement section (1) used for the flow measurement of fluids. It is equipped with two ultrasonic transmitting and receiving transducers (2, 3) spaced in the fluid flow direction and is characterized in that the sound is guidable in Z-shaped manner between the transmitting and receiving transducers (2, 3) by means of at least two reflectors (4). A description is given of a corresponding measurement method and a method for the one-piece production of a measurement section (1) by injection moulding.
