Flow Sensors (for water and other fluids)

What is it?

Flow sensors for water and other fluids are devices that measure the volume or rate of fluid flow in a pipe or conduit. They detect and monitor the flow of fluids, which can be important for optimizing system performance and reducing energy consumption.

Why we use it?

We use flow sensors to maintain good system performance, optimize energy usage, detect leaks, and comply with building codes and standards.

How it works?

The sensor typically contains a sensing element, such as a turbine, paddle wheel, or ultrasonic transducer, which interacts with the fluid flow to produce a signal proportional to the flow rate or volume. The device then calculates the flow rate or volume based on the magnitude of the signal produced.

Major brands that manufacture it

Some of the major brands that manufacture flow sensors for water and other fluids include Siemens, Schneider Electric, Honeywell, and Johnson Controls.

Types

There are different types of flow sensors, including mechanical, electromagnetic, and ultrasonic models. The selection of the appropriate sensor type depends on the specific application, fluid type, measurement range, accuracy requirements, and other factors.

How do we select it?

When selecting a flow sensor, consider factors such as accuracy, measurement range, response time, pressure drop, compatibility with the fluid type, and communication protocols. Also, make sure the sensor is compatible with your existing plumbing and building automation systems.

How to install it?

Flow sensors should be installed in the pipeline or conduit where fluid flow needs to be measured. They should be mounted securely in the horizontal or vertical position according to the manufacturer's recommendations, and any necessary fittings or adapters should be used to connect the sensor to the pipeline or conduit.

Wire connections required to receive the signals

The wire connections required to receive the signals from a flow sensor may vary depending on the specific device and building automation system. Typically, they will require a power supply connection and a communication signal wire that connects to the building automation system or controller. It's important to refer to the manufacturer's installation instructions for proper wiring connections.
