Problems solved by technology

Despite the advantages described, this technical solution also has the disadvantages of: smaller cross-section of the fluid flow; distortion of the flow structure due to the recoil of the flow on the surface of one of the bases of the lumen; Measuring channel of greater length to regulate flow; use of only one (ultrasonic) method for measuring flow velocity; use of inseparable structure of the measuring chamber

Embodiment Construction

[0035] The fluid meter consists of the following components ( Figure 1a and 1b ):

[0036] - a cylindrical housing 1 with a cavity 2 and a bottom with an inwardly curved portion 3 in a structure which enables the formation of a fluid flow,

[0037] - a flow meter 4 of any mode of action, said flow meter being located in the central part of the housing 1 of the meter and for measuring the flow velocity of the fluid, wherein the flow meter 4 has a funnel-shaped inlet,

[0038] - connecting means 5 for adapting the different diameters of flowmeter and gauge outlets,

[0039] - a flow preparation device 6 for separating and stabilizing the fluid flow,

[0040] - input channel 7 for fluid flow,

[0041] - output channel 8 for the fluid flow from the meter,

[0042] - electronics unit 9,

[0043] - a coarse filter 10 in the input channel 7,

[0044] - shut-off valve 11 in input channel 7 and

[0045] - Fluid leakage recognition sensor 12 .

Description

technical field [0001] The invention relates to a fluid meter for flow measurement. Background technique [0002] There are different principles and technical solutions for realizing the measurement of the flow rate of a fluid flowing through a measuring instrument. [0003] Some solutions known from the prior art are described, for example, by documents DE 20 2014 007 095 U1, EP 1909 076 A1, EP 2 375 224 A1, US 4 715 234 A, US 8 776 613 B2 and WO 2012 152 560 A1 A gauge whose function is based solely on the volumetric principle. [0004] Mechanical turbine meters and rolling piston meters are among the meters that work according to the volumetric principle. The advantage of a mechanical turbine meter is its resistance to flow disturbances and flow distortions of the fluid flowing through it and its insensitivity to flow reversals. The main disadvantage of the mechanical measuring method of the meter lies in the moving parts, which are susceptible to contamination substan...
