Flow Sensors & Indicators
Flow Sensors & Indicators are critical components in various industries and applications that require accurate and reliable measurements of fluid flow rates. These sensors and indicators measure the flow of liquids and gases in pipes, tubing, and other conduits. They help ensure that processes are running smoothly and efficiently while also detecting any abnormalities that may indicate a problem in the system.
Types of Flow Sensors:
There are several types of flow sensors, including:
- Differential Pressure Flow Sensors - These sensors measure the pressure difference between two points in the flow system and use this information to calculate the flow rate.
- Turbine Flow Sensors - These sensors use a rotor with blades that rotate as fluid flows through the system. The rotation speed is proportional to the flow rate.
- Electromagnetic Flow Sensors - These sensors use Faraday's law of electromagnetic induction to estimate the flow rate of conductive fluids.
- Ultrasonic Flow Sensors - These sensors use ultrasonic waves to measure the velocity of the fluid in the pipe and calculate the flow rate.
Applications of Flow Sensors:
Flow sensors are used in various applications across many industries, including:
- Industrial Processes - Flow sensors are used in industrial processes such as chemical processing, water treatment, and power generation to ensure the flow rates of liquids and gases are within acceptable limits.
- HVAC Systems - Flow sensors are used in heating, ventilation, and air conditioning systems to monitor airflow and ensure proper circulation.
- Automotive Industry - Flow sensors are used in automotive systems such as fuel injection and exhaust gas recirculation systems to monitor flow rates and ensure proper operation.
- Medical Industry - Flow sensors are used in medical equipment such as oxygen concentrators, anesthesia machines, and respiratory therapy equipment to monitor and control the flow of gases.
Types of Flow Indicators:
Flow indicators are devices that visually indicate fluid flow through a system. There are several types of flow indicators, including:
- Rotameters - These devices use a tapered tube with a float that rises as fluid flows through the system.
- Sight Glasses - These devices use a transparent window to allow operators to visually inspect a fluid flow.
- Flow Switches - These devices are used to detect the presence or absence of flow and can be used to trigger alarms or other actions.
Applications of Flow Indicators:
Flow indicators are used in many of the same applications as flow sensors, including industrial processes, HVAC systems, automotive systems, and medical equipment. They visually indicate fluid flow through the system, allowing operators to quickly identify any abnormalities or issues.

Honeywell Zephyr™ HAF Series – High Accuracy ±50 SCCM to ±750 SCCM
Honeywell Zephyr™ HAF Series sensors provide a digital interface for monitoring airflow over specified full-scale flow and compensated temperature ranges. The thermally isolated heater and temperature sensing elements help these sensors provide a fast response to air or gas flow.
Zephyr sensors are designed to measure mass flow of air and other non-corrosive gases. Standard flow ranges are available at ±50, ±100, ±200, ±400 or ±750 sccm. Custom flow ranges are also available. The sensors are fully calibrated and temperature compensated with an onboard Application Specific Integrated Circuit (ASIC).
The HAF Series is compensated over the temperature range of 0°C to 50°C and operates across a temperature range of -20°C to 70°C. The state-of-the-art ASIC-based compensation provides digital (I2C) outputs with a response time of 1 ms.
These sensors operate on the heat transfer principle to measure mass airflow. They consist of a microbridge Microelectronic and Microelectromechanical System (MEMS) with temperature-sensitive resistors deposited with thin films of platinum and silicon nitride. The MEMS sensing die is located in a precise and carefully designed airflow channel to provide repeatable response to flow.
Zephyr sensors provide the customer with enhanced reliability, high accuracy, repeatable measurements and the ability to customise sensor options to meet many specific application needs. The combination of rugged housings with a stable substrate makes these products robust. They are designed and manufactured according to ISO 9001 standards.
Features and Benefits
Total error band as low as ±0.25%
Fast response time

LG01-2000A090, Sensirion
LG01-2000A Liquid Flow Switch & Bubble Detectors
The LG01-2000A family of liquid flow switches from Sensirion are able to detect liquid flow by millilitres per minute (ml/min). It also provides bubble detection.
When the flow rate is more than the desired flow switch point, the output signal is 5 V. If the flow rate is lower than this point the output signal is 0 V. This is also the case for when air/bubbles are sensed within the sensors flow channel.
This non-invasive liquid flow switch has a straight glass capillary flow path. This also enables chemical resistance and bio-compatibility.
An additional Connectivity Kit can be purchased separately for the LG01 liquid flow switches.
