An instrument that measures the rate of flow of a liquid or gas is called a mass flow sensor. Users might need to utilize this tool when they have a material to measure in order to get an accurate reading. For users to understand the fundamentals of mass flow sensors, below is a brief guide.

Describe The Mass Flow Sensor

A tool used to gauge the mass flow rate of a fluid is called a mass flow sensor. This sensor is applicable to the chemical, oil and gas, food and beverage, and water treatment industries. The sensor makes use of a detecting component to identify changes in pressure brought on by fluid flow. The sensor can calculate the fluid’s mass flow rate by monitoring this change.

What Varieties Of Saftty Mass Flow Sensors Are There?

1.Differential pressure flow sensor: As an illustration, consider the ADP2000 differential pressure sensor. The internal thermal sensor portion of the ADP2000 sensor, a digital differential pressure sensor, detects the differential pressure of the gas passing through it. This sensor can measure the pressure difference between air, nitrogen, and oxygen with high precision and without drift. It offers a -125 to +125Pa differential pressure range, great precision at low differential pressure, high reliability, and long-term stability.

2.The AMC2000 Gas Mass Flow Controller is a tool for accurate gas mass flow monitoring and control. The sensor uses a self-designed MEMS mass flow chip that is accurate, stable, and has the qualities of strong linearity, quick reaction time, and resistance to both high and low temperatures.

How Does It Function?

Different flow sensor types operate according to various working principles. Here are the first three:

1.Differential pressure flow sensor: This device has a lengthy history of production and is often used. The differential pressure flow sensor’s basic operation is to measure the pressure difference value that appears before and after the fluid passes through the pipeline’s built-in throttling section. This value corresponds to the flow rate and may be used to calculate the flow rate. Its traits include tight installation requirements and highly precise machining on the throttling parts. To ensure that the fluid flow is stable, there must be long enough straight pipes both before and after it. This kind of flow sensor is used at Saftty.

2.Mass flow sensor: Mass flow sensors are frequently used to monitor both liquid and gas flow. This sensor establishes a functional link between fluid mass flow and fluid force using the principles of fluid mechanics. It works best for liquid measuring. To ensure that the mass flow is within the measuring range for gas measurements, high pressure is necessary. As long as the pipeline diameter is smaller than 200mm, it can be used for measurements.


The mass flow sensor is a precision tool used in many different professional domains to measure the mass and flow of liquid or gas. Users can gain more knowledge about mass flow sensors and how to utilize them by reading this tutorial and using the example of Saftty.
