V cone flowmeter
Product name: v-cone flowmeter
Product introduction: The characteristics of traditional differential pressure meters are based on ideal flow conditions; in fact, such conditions do not exist in real applications. Any changes in piping layout, such as elbows, valves, reduced diameters, enlarged diameters, pumps, tee joints, etc., will destroy the fully developed flow. It is difficult for general flow meters to obtain correct measurement values in turbulent flow. The V-cone flowmeter overcomes these shortcomings. Under extremely harsh installation conditions, if there are two upstream elbows that are not on the same plane and are very close to the cone, the V-shaped cone can also make the speed distribution flat and symmetric, thus ensuring the measurement accuracy. Because the orifice edge of the V-cone flowmeter is obtuse, the flow

Product classification and structure According to the scope of product supply and the output signal, the V-cone flowmeter can be divided into 3 categories:
1. The V-cone flow sensor only provides the forming part of the differential pressure signal (throttle parts and pipes), and does not provide the differential pressure transmitter and flow display part, and the output signal is differential pressure. It is up to the user to make other configurations.
2, V-cone flow transmitter
consists of a V-cone flow sensor and a differential pressure transmitter. There are two structures, split installation and integrated installation.
The split V-cone flow transmitter is composed of an independent V-cone flow sensor and a differential pressure transmitter. The pressure pipe connection between the V-cone flow sensor and the differential pressure transmitter is completed by the user.
Integrated installation means that the differential pressure transmitter and the V-cone flow sensor have been connected into one when the product leaves the factory. After the user purchases the integrated V-cone flow transmitter, there is no need to connect the pressure pipe when using it. However, the corresponding flow totalizer, pressure transmitter and temperature transmitter must be connected.
3, V-cone flowmeter
There are two structures of split installation and integrated installation:
Split installation is composed of independent V-cone, differential pressure, pressure, temperature transmitter, flow calculator, stop valve and other parts. The connection combination between the various parts is completed by the user himself. There are two kinds of explosion-proof type and ordinary type
