Abstract
The utility model relates to an integral electric vortex flow meter used in petroleum field, chemical industry and metallurgical industry. The integral electric vortex flow meter consists of an alnico, a triangle vortex generator, a shell, a probe, a locking bracket, a tie-in and an electric vortex integrating instrument. The triangle vortex generator is arranged inside the shell; the probe is arranged inside the locking bracket welded on the top surface of the shell, with the round orifice extending into the shell. The probe is provided with a wire tie-in at the upper end and is connected with the electric vortex integrating instrument which is arranged above the probe. The alnico is arranged inside an alnico sleeve which is welded at the bottom of the shell. Structurally, the flow meter ensures that the fluid which is taken as conducting medium can develop into a vortex after running through the triangle vortex generator and causes transverse vibration to incise the electromagnetic field; then electric signals can be detected by a sensor under the corresponding induced electromotive force; in this way, the flux of the fluid can be precisely measured. The integral electric vortex flow meter is suitable for various fluid medium in large pressure range and is particular suitable for metering the flow of high pressure infusion water and sand-carrying water in oil fields; the integral electric vortex flow meter is reliable in work and precise in metering and is safe.
