Problems solved by technology

[0007] However, when channel dividers are incorporated into existing vibrating meter designs, such as in multi-channel flow tubes with circular diameters, the channels reduce the cross-sectional area available for flow through the flow tubes.

Embodiment Construction

[0056] The present disclosure describes a vibrating meter including a flow tube having a pointed section and a method of forming a vibrating meter including a flow tube having a pointed section.

[0057] figure 1 A vibrating meter 5 is depicted with a multi-channel flow tube 130 according to an example. Such as figure 1 As shown in , the vibrating meter 5 includes a meter assembly 10 and meter electronics 20 . The meter assembly 10 is responsive to the mass flow rate and density of the process material. Meter electronics 20 is connected to meter assembly 10 via leads 100 to provide density, mass flow rate and temperature information, among other information, via communication path 26 . Information and commands may also be received at meter electronics 20 via communication path 26 .

[0058] A Coriolis flowmeter structure is described, although this is not intended to be limiting. The skilled artisan will readily appreciate that the present application may be practiced a...

Abstract

First and second vibrating meters (5) and methods of manufacturing the same are provided. The first vibrating meter includes: a sensing element (170l); a driver (180); and a flow tube (400) including a tube peripheral wall having: a first substantially planar section (406a); a second substantially planar region segment (406b) coupled to the first substantially planar segment to form a first angle θ 1 (404); and the first curved section (406c). The second vibrating meter includes: a sensing element; a driver; and a flow tube (700) including a tube peripheral wall having: a first substantially planar section (706a); a second substantially planar section (706b) coupled to a first substantially planar segment to form a first angle θ 1 ( 704 ); third substantially planar segment ( 706c ); fourth substantially planar segment ( 706d ); and fifth substantially planar segment ( 706e ).

Description

technical field [0001] The examples described below relate to vibrating meters and flow tubes for vibrating meters. More particularly, examples relate to vibrating meters including flow tubes with pointed sections. Background technique [0002] Vibrating meters, such as Coriolis mass flow meters and vibrating density meters, typically operate by detecting the motion of a vibrating flow tube containing a flowing material. Properties associated with the material in the flow tubes, such as mass flow, density, etc., may be determined by processing measurement signals received from motion transducers associated with the flow tubes. Vibration meters have gauge assemblies with one or more flow tubes in a straight configuration or a curved configuration. Each flow tube configuration in a Coriolis mass flow meter has a set of natural modes of vibration, which can be of the simple bending type, torsional type, or coupled type. Each flow tube can be driven to oscillate in a preferre...
