1. Balanced flowmeter vs orifice flowmeter: Understanding the core differences in 3 minutes

The core differences between balanced flowmeter and orifice flowmeter lie in their structural design, performance characteristics, and applicable scenarios. The former uses a porous symmetrical design to achieve efficient and stable measurement, while the latter provides a simple and economical solution with a single pore structure.

1. Structural design difference balance flowmeter: a new type of instrument based on differential pressure principle, with multiple symmetrical small holes distributed on the throttling element.

. When the fluid flows through, the porous structure evenly distributes the fluid pressure, reduces eddy currents and kinetic energy losses, and forms a stable pressure difference for flow calculation. Orifice flowmeter: a commonly used differential pressure measuring instrument with a metal thin plate with a central circular hole as the throttling element. When the fluid passes through a circular hole, a sudden change in flow velocity leads to a pressure difference, which is used to deduce flow data. Key difference: The porous design of balanced flow meters optimizes the fluid flow state, while the single pore structure of orifice plate flow meters can easily cause severe disturbances.

2. Performance Characteristics Comparison Pressure Loss and Energy Consumption Balance Flow Meter: The porous structure reduces eddy current and kinetic energy loss, and the permanent pressure loss is much lower than that of the orifice plate flow meter. Long term operation can reduce the energy consumption of pump equipment, and the energy-saving effect is significant.

. Orifice flowmeter: The sin Selection of Plate Hole Flow Meter

gle orifice design causes severe fluid disturbance, high pressure loss, and increased energy consumption costs. Measurement accuracy and stability balance flowmeter: The measurement accuracy reaches ± 0.5%, and it can maintain high stability even when the flow rate is unstable or the medium contains a small amount of impurities. It has a wide range ratio and is suitable for complex working conditions. Orifice flowmeter: The accuracy is greatly affected by flow rate fluctuations and medium cleanliness, and its performance is reliable in stable working conditions and clean medium scenarios. Anti clogging ability balance flowmeter: The porous structure is not easily blocked by impurities, and the dirt resistant design reduces maintenance frequency. Orifice flowmeter: Single hole is prone to impurity accumulation and needs to be cleaned regularly to maintain accuracy.

III. Application scenario analysis: High precision measurement scenarios of balanced flow meters, such as natural gas trade settlement and precision chemical process control, can meet strict measurement requirements with an accuracy of ± 0.5%.

. Complicated working environment: In high-temperature and high-pressure steam systems, as well as medium measurements containing small amounts of impurities, the stability is better than that of orifice flow meters. Long term energy-saving demand: Low pressure loss characteristics can reduce energy consumption of pump equipment, suitable for energy metering upgrade scenarios. Basic measurement scenarios for orifice flow meters: scenarios that do not require high accuracy, have relatively clean media, or can be regularly cleaned, such as routine monitoring of civil water supply systems.
