What is the difference between flange type and clamp type vortex flowmeter?
Vortex flowmeter clamping type refers to the situation where the flowmeter body does not have a flange, the pipeline has a flange, and the pipeline is tightened with bolts to firmly clamp the flowmeter inside, so it is called clamping.. The flange type has flanges on both the body and the pipeline, and is fixed and installed by a pair of flanges, so the clamping pressure and diameter are not high. But Jie Xiang secretly arranged for 2 flanges, which can be cheaper or much lighter for transporting dry goods.
2. Do you know the internal structure of vortex flowmeter?
The vortex flowmeter is an instrument for measuring fluid flow based on the vortex effect. Its internal structure is precise and its functions are clear. It mainly consists of the following parts:
1. Flow channel part: The diffuser is composed of an inlet, an outlet, and an intermediate flow channel.
. The inlet and outlet are circular channels, and the middle channel is a circular cavity to ensure smooth fluid flow. Function: Provide a stable flow path for fluids, reduce turbulence interference, and ensure measurement accuracy.2. Position and shape of vortex generator: Installed perpendicular to the axis of the measuring pipeline, the common shape is a triangular cylinder (the most widely used).
. Function: When fluid flows through, Karman vortex streets (periodic vortices) are alternately generated on both sides of the body, and their frequency is proportional to the flow velocity, which is the core basis for flow measurement. Key point: Geometric parameters such as width and angle directly affect the stability and flow characteris
3. Type of detection element: sensitive elements such as thermosensitive, strain sensitive, magneto electric, capacitive, photoelectric, etc. are used, and Anxian is only installed on the housing.
. Function: Detect Karman vortex street signals and convert periodic vibrations into electrical signals (such as voltage and frequency). Example: Thermistors monitor temperature fluctuations caused by vortices and output signals related to flow velocity.Fourth, the core components of the vortex street sensor include measuring electrodes, vibration rods, and brackets.
. Working principle: The vortex impact vibration rod generates periodic vibration, and the measuring electrode captures the vibration signal and converts it into an electrical signal. Output: The signal frequency is proportional to the fluid flow velocity and is used for subsequent flow calculation.Fifth, rotor (some models) structure: composed of a turbine and bearings, located inside the sensor.
. Function: The fluid impacts the turbine to rotate, and the rotational speed directly reflects the flow velocity (some models use rotor assisted measurement). Characteristics: High precision bearings are required to reduce friction and ensure a linear relationship between speed and flow rate. 6、 Terminal function: Transmit sensor signals to external devices. Configuration: Usually includes two cables: power cord: supplies power to the sensor (such as 24V DC). Signal line: transmits vibration frequency signals (such as 4-20mA current or pulse signals). 7、 Shell and auxiliary structure shell: made of metal material, protecting internal components from mechanical damage, corrosion, and electromagnetic interference.
