Structure and use of porous balanced flowmeter

Project Overview

Main structural components of HSP balance flowmeter

1. Throttle: The core component of the flowmeter. Its shape and size have a great influence on the measurement accuracy.

2. Differential pressure transmitter: used to measure the pressure difference on both sides of the orifice plate and convert the pressure signal into an electrical signal.

3. Three-valve group: Connect or block the positive and negative pressure measurement chambers of the differential pressure transmitter and the positive and negative pressures introduced by the throttling device to facilitate installation, disassembly, and daily maintenance by technicians.

4. Flange: used to connect orifice plates and pipes, usually threaded or welded.

5. Flow totalizer: used to display and record flow values.

Measurement advantages of HSP balance flowmeter

1. High linearity and good repeatability

The balanced orifice flowmeter has the characteristics of symmetrical porous structure and can convection The field is balanced, eddy current, vibration and signal noise are reduced, and the stability of the flow field is greatly improved.

2. Reduce permanent pressure loss

The porous symmetrical balance design reduces the formation of turbulent shear force and vortex, and reduces the loss of kinetic energy. Under the same measurement conditions, Compared with the orifice plate, the permanent pressure loss is reduced by 2.5 times, thus saving considerable operating energy costs. It is an energy-saving instrument.

3. Resistant to dirt and not easy to blockage

The porous symmetrical balanced design reduces the formation of turbulent shear force and vortex, thereby greatly reducing the formation of retention dead zones and ensuring Dirty media passes through multiple holes smoothly, reducing the chance of fluid holes being clogged.

4. Good long-term stability

Due to the obvious reduction of turbulent shear force, the direct friction between the medium and the throttling member is greatly reduced, and its other value is long-term stability. Remaining unchanged, the entire instrument has no moving parts, thus maintaining long-term stability.

5. It can measure media under complex working conditions

Due to its special structural design, it has special performance. It can measure gas-liquid two-phase, mud, and even solid particles. . Balanced flow can measure bidirectional flow.
