Flow Switches & Flow Meters: Affordable Innovation in ifm’s Flow Technologies
ifm’s price/performance philosophy helps customers compete in their business every day. For more information about ifm flow sensors, visit the ifm flow switches and flow meters page.
Affordable innovation: sounds like an oxymoron, but for ifm engineers, it’s a guiding design philosophy. Ten years ago, the cost difference between a mechanical flow switch and an ifm sensor was substantial. Today, ifm’s sensor prices have reduced considerably to the point where they can easily replace mechanical switches throughout a plant. ifm’s flow sensing products are a great example of this transition. The product line continues to be re-engineered for today’s critical flow applications. Housings are smaller, flow technologies more precise, and prices have dropped considerably. ifm’s flow sensing technologies can be divided into two principles of operation: thermal flow sensing and flow metering.
ifm’s flow sensors apply thermal flow sensing principle to monitor the flow rate of liquids and gases. The thermal sensing principle uses the cooling effect of a flowing fluid or gas to monitor the flow rate. The amount of thermal energy that is removed from the sensor tip determines the local flow rate. This temperature-based operating principle can reliably sense the flow of virtually any liquid or gas. Because there are no moving parts to jam or break, ifm flow sensors eliminate the maintenance headaches of flapper-style mechanical flow switches.
A traditional flow magmeter can be considered out-of-reach for a standard flow application because of its $2000+ price tag. To address the issue, ifm’s engineers design flow meters that use magnetic inductive or ultrasonic technologies to monitor critical flow applications. The SM Series flow magmeter applies magnetic inductive flow technology which is based on Faraday’s Law of electromagnetic induction to detect the flow velocity of an electronically conducting fluid through a pipe diameter. The SU Series ultrasonic flow meter is based on the differential transit time principle. Both compact products can be easily installed in an application at a price point that enables the meters to be used throughout a plant.
