The V-cone flowmeter, like other differential pressure instruments, is also based on the principle of flow continuity and Bernoulli equation to calculate the flow rate of fluid conditions. We know that in the same closed pipeline, when the pressure decreases, the velocity will increase. When the medium approaches the cone, its pressure is P1. When the medium passes through the throttling area of the cone, the velocity will increase and the pressure will decrease to P2. As shown in the figure, both P1 and P2 are led to the differential pressure transmitter through the pressure port. When the flow rate changes, the differential pressure value will increase or decrease accordingly. That is to say, for stable fluids, the magnitude of the flow rate is directly proportional to the square root of the differential pressure. When the flow rate is the same, the larger the cone throttling area, the greater the differential pressure value generated.

The permanent pressure loss is low, and only one-third of the orifice plate is familiar with the Venturi tube.
The range is much wider than that of other differential pressure types, with a normal range of 10:1.
The accuracy of the V-cone flowmeter with high measurement precision is ± 0.5%.
The repeatability of the V-cone flowmeter with good repeatability is ± 0.1%.
The requirements for straight pipe sections are low, only requiring extremely short straight pipe sections (front 1-3D, back 0-1D).
The structure design of the self rectifying, self-cleaning, and self-protection flowmeter is a fluid sweep type structure, with no dead corners of scale accumulation. The boundary layer effect formed by the unique structure prevents wear on key parts of the throttle component.
Anti vibration, high temperature, and high pressure flow sensors are pure mechanical bodies without moving parts, so they are resistant to high temperature, high pressure, corrosion, and vibration.
The integrated structure design of the V-cone flowmeter integrates the throttling element, sensor, intelligent circuit, display, and communication unit. During installation, users only need to weld the matching flange, which eliminates the pressure pipeline of traditional differential pressure flowmeters, simplifies installation, reduces installation time and cost, and is convenient for users to use.

Flange execution standards: JB/T81-1994, JB/T82.1-1994, JB/T82.2-1994

The V-cone flowmeter can work normally even under harsh conditions, but for long-term safe and stable use, please pay attention to the following points during installation:
(1) The installation site shock and vibration V-cone flowmeter is designed to withstand a certain degree of shock and vibration when it leaves the factory. But it should also be installed as much as possible in places with no or minimal vibration.
(2) Please try to avoid installing the flowmeter in places with large temperature changes. If the installation location is directly exposed to thermal radiation or sunlight, waterproof, thermal insulation, radiation and ventilation measures should be taken.
(3) The installation site environment air conditions for V-cone flow meters should be avoided as much as possible in corrosive environments. If used in corrosive environments, good ventilation should be provided and attention should be paid to avoiding corrosive gases or liquids from entering the instrument.
