How to assemble several components of V-cone flowmeter in differential pressure flowmeter? The accessories of the V-cone flowmeter consist of four main components: pressure transmitter, three valve group, needle valve, and flow sensor. If it is the Minbu high-temperature bridge cover ear, it also consists of a condenser tank.

What should be noted when installing a 2. V cone flowmeter?

Preparation for installation of V-cone flowmeter: 1. Before installation, it is necessary to check the packing list of the flowmeter, compare the manufacturers calculation book to check the opening of the V-cone flowmeter and the range of the differential pressure transmitter. Secondly, it is necessary to ensure the length of the first 3 times the diameter of the pipeline and the last 1 time the diameter of the pipeline during on-site installation.

2. Correctly use sealing gaskets, use appropriate specifications of screw nuts and spring washers, and gradually tighten them symmetrically and evenly.

3. It can be installed horizontally, vertically, or obliquely in chambers, and the pipeline should be filled with medium fluid.

3. Do flow meters in instruments require installation of straight pipe sections? I only know that the V-cone is front 3D and back 1D, please be large According to the GB 50093-2002 Code for Construction and Acceptance of Automation Instrumentation Engineering, the required length of the front and rear straight pipe sections for different types of flow meters is different. The usual requirements for the upstream and downstream straight pipe sections of the flow meter are as follows: - Rotary flow meter, upstream not less than 0-5 times the pipe diameter, downstream no requirements; ——Target flowmeter, with an upstream diameter not less than 5 times the pipe diameter and a downstream diameter not less than 3 times the pipe diameter; ——Turbine flowmeter, with an upstream diameter not less than 5-20 times the pipe diameter and a downstream diameter not less than 3-10 times the pipe diameter; ——Vortex flowmeter, with an upstream diameter not less than 10-40 times the pipe diameter and a downstream diameter not less than 5 times the pipe diameter; ——Electric noise potato magnetic flowmeter, upstream not less than 5-10 times the pipe diameter, downstream not less than 0-5 times the pipe diameter; ——Ultrasonic flowmeter, with an upstream diameter not less than 10-50 times the pipe diameter and a downstream diameter not less than 5 times the pipe diameter; ——Positive displacement flowmeter, no requirements; ——Orifice plate, upstream not less than 5-80 times the pipe diameter, downstream not less than 2-8 times the pipe diameter; ——Nozzles, with upstream diameter not less than 5-80 times the pipe diameter and downstream diameter not less than 4 times the pipe diameter; ——Venturi tube, bent tube, wedge-shaped tube, upstream not less than 5-30 times the pipe diameter, downstream not less than 4 times the pipe diameter; ——Uniformity pipe, with an upstream diameter not less than 3-25 times the pipe diameter and a downstream diameter not less than 2-4 times the pipe diameter.
