What Is Liquid Mass Flow Controller?

Liquid flow controllers can be used to measure and control the flow rate of various types of liquids.

Liquid flow controllers are typically used in applications that require a constant flow rate and can compensate for changing pressure changes. Because of this feature, liquid flow controllers cost more than liquid flow meters that typically only measure flow. Read more about: The Pros and Cons of Micro Motion Flow Transmitters

FAQ

Generally speaking, when only measuring or monitoring the flow, use a mass flow meter. When you need to control the flow, use a mass flow controller.

In some measurement occasions, both can be used. For example, when measuring the flow capacity of the capillary tube, when measuring the flow at constant pressure, use a mass flowmeter.
When measuring pressure with constant flow, a mass flow controller is required.

Note that when the mass flow controller is in the cleaning state, it can also be used as a mass flow meter, but the pressure drop is larger than that of an ordinary mass flow meter.

Mass flow controller, namely Mass Flow Controller (abbreviated as MFC). Not only has the function of a mass flow meter. More importantly, it can automatically control the gas flow. That is, users can set the flow rate according to their needs. MFC automatically keeps the flow constant at the set value. Even if the system pressure fluctuates or the ambient temperature changes, it will not deviate from the set value.

Simply put, the mass flow controller is a steady flow device. It is a gas steady flow device that can be set manually or automatically controlled by connecting with a computer.

Mass flow meter, namely Mass Flow Meter (abbreviated as MFM). It is an instrument for accurately measuring gas flow. The measured value is not inaccurate due to temperature or pressure fluctuations, and does not require temperature and pressure compensation.

The mass flow controller is composed of a flow sensor, a diverter channel, a flow regulating valve and an amplifying controller.

The flow sensor uses the principle of capillary heat transfer thermometry to measure the mass flow of gas (without temperature and pressure compensation). The flow signal measured by the sensor heating bridge is sent to the amplifier to be amplified. The amplified flow detection voltage is compared with the set voltage. Then the difference signal is amplified to control the regulating valve. Closed loop control of the flow through the channel to make it equal The set flow is equal.

The flow divider determines the flow of the main channel. The flow indicator matched with the mass flow controller is equipped with a regulated power supply, a digital voltmeter, setting potentiometer, peripherals, internal conversion and three-position valve control switch, etc.
