What do you expect for water and other liquids?

The amount of flows of water, oil, coolant and many other media must be controlled and monitored in certain environments. In cooling circuits, pump or pump systems as well as heating systems, the values ​​obtained protect the machines from damage that can result from a lack of cooling or lack of lubrication. For example, the dry run can be identified in good time and prevent the consequences preventively.

Typically, flow guards are installed in lines and pipes to monitor the flow of liquid media. There are mechanical and electronic variants that either rely on movable components or work without contact.

Good to know: A robust construction by the flow guard is essential, especially in aggressive media, high pressure or extreme temperatures.

How are flow guards used for liquid media?

Thermal flow guards are based on temperature differences. Here a sensor is heated, while a second measures the ambient temperature. If the liquid flows, it transports heat, which reduces the temperature difference. If the flow drops under a defined value, the sensor triggers a signal.

Mechanical flow guardsLike paddle guard, rely on movable elements. The flow presses on a paddle, a flap or a piston that moves proportionally to the flow strength. If a limit is below the limit, the element returns to the starting position and activates a switch.

If the flow is measured by changing the electrical properties, think of inductance or capacity, we speak of electronic and inductive flow guards for water. Electronic variants measure the flow using sensors and work according to the inductive or magnetic principle.

In inductive variants, the liquid flow is monitored using a magnetic field. If the flowing medium has metal particles or magnetic properties, it affects the field and creates a signal. In ultrasonic sensors or optical sensors, the movement of the medium is recorded by sound waves or light reflections. The signal change shows whether there is a flow.

Ultimately there is still the Different pressure flow guards for liquid media. In certain systems, the water flow is monitored via a throttle point in the tube. The pressure difference that arises before and after the throttle point is set in direct ratio to the flow and can be used as a measurement variable using a pressure switch reacting to it.

Why rely on a water flow guard?

The flow monitoring of liquids is essential in many areas of industry and production to prevent damage to machines and systems. Cooling circuits, heating systems or pumps are dependent on a constant fluid flow. If the flow stops or is too low, the failure or overheating of engines, pumps or heat exchangers quickly occur. The flow guard immediately recognizes when the water flow falls below a critical value. This means that machines can be switched off automatically before expensive damage.

Depending on the operating mode, depending on the water flow, the process stability is also to ensure uniform conditions. Otherwise, deviations can affect the quality of the end product. An example of this is classic food production, in which water is often used for cooling or as part of the product.

In addition, the flow monitoring of liquid media is characterized when it comes to energy efficiency and resource optimization. An uncontrolled or interrupted water flow often leads to unnecessary energy consumption or a waste of resources because pumps or systems continue, although there is no flow. If no water flow is recognized, the system switches off automatically or regulates the power.

Operational safety and the risk of downtimes can also be controlled efficiently with a flow guards for water. With their simple installation and the versatile possible uses, they are suitable for different applications. And do not forget the economic side, because an early detection of flow problems prevents expensive repairs or production stilings.

Where is the flow surveillance used for liquids?

A typical of the area of ​​the flow of flowers are cooling circuits in machines and production systems, in which cooling water must continuously circulate in order to protect engines, heat exchangers or other components from overheating.

In heating and air conditioning systems, flow monitoring is used to ensure that water or heat carriers flow in the lines. In this way, heating systems can work efficiently. In water treatment and chemical industry, monitoring the fluid current is essential to ensure the smooth operation of pumps, filters or dosing systems.

In the food and beverage industry, a flow guard ensures water that cooling, cleaning or production fluids are available in the required quantities and the hygiene regulations are observed.

Discover our flow guards for water

The focus is on precision and reliability in our flow guards in order to meet their highest demands. Therefore you can find in our productCollections Only selected models that have individual solutions for you.

The Water and air flow guards RLSW®7 convinced by its robust construction and a stainless steel sensor housing, so that the flow guard can be used in demanding industrial environments. Equipped with a relay output and a highly sensitive sensor, it enables precise monitoring of water and air currents. The switching points are infinitely adjustable for liquids (0.03… 3 m/s) and gases (0.5… 20 m/s). The TÜV-Nord certification according to DIN EN 61010-1: 2011-07 underlines the high security standards.

The Flow guard NLSW®45-4 Thanks to its switching exit (1 NO/1 NC), it is ideal for the control cabinet installation. Together with the right one Feeler F6, which is optionally available with a stainless steel sensor housing, it creates a large measuring range and continuously adjustable switching points for liquids and gases. This model also meets the high requirements of TÜV-Nord certification.
