Common connection methods for flow meters

2019-05-06

Word Size

Flow meters are used to measure the flow rate of fluids, including gases, liquids, and steam. Different types of flow meters have been developed to meet various needs, such as rotor flow meters, electromagnetic flow meters, vortex flow meters, and orifice plate flow meters. Each type of flow meter has its own operational requirements and installation methods. This article briefly introduces the different connections of flow meters.

I. Flange Connection

Flange connection is probably the most common connection method. The ACU100L pipeline thermal mass flow meter and ACU10FD thermal mass flow controller are both available with flange connections; simply secure the flanges at both ends to the pipe flanges with bolts.

II. Threaded Connection

Some flow meters use threaded connections, including glass rotor flow meters, gold rotor flow meters, and turbine flow meters.

III. Clamp Connection

Flow meters without flanges often use this connection method. They can be clamped to both sides of the pipe base with bolts, making this a relatively simple connection method. Many vortex flow meters use this connection method.

IV. Sanitary Clamp Connection

This connection is now used for some small-diameter pipes with low operating pressures. This connection allows for quick installation and removal of the flow meter, and makes daily cleaning and maintenance convenient. Suitable for liquids with uniform, liquid-solid two-phase suspensions, such as mud, slurry, and pulp.

V. Other Types

In addition to the above, there are many other types of connectors. Some miniature flow meters use compression fittings, pagoda connectors, latex tube connectors, quick-connect connectors, and quick-release connectors.

ACU10FDR

ACU10FDR

The ACU10FDR low differential pressure gas mass flow controller, equipped with a proprietary high-flow electromagnetic valve, is suitable for controlling mass flow in situations with minimal available system pressure. The low differential pressure ensures minimal impact on the system, enabling flow control under near-atmospheric pressure conditions and reducing system response time. We will customize the valve and PID control functions for you based on your application parameters to ensure that the product can achieve fast and stable control while maintaining low pressure loss.

ACU10FC

ACU10FC

The ACU10FC differential pressure mass flow controller uses a differential pressure mass measurement principle with no thermal drift and no response lag. It can simultaneously display and output: instantaneous flow rate, cumulative flow rate, pressure, temperature, etc. When a control function is required, an electromagnetic proportional control valve and built-in PID control function can be added. Unlike thermal flow meters, the ACU10FC has no additional "specific heat capacity" error when using gas conversion coefficients. Therefore, even if the measured gas is different from the calibration gas at the factory, it will not affect the measurement accuracy.
