Sensor Element/Probe: Flow Range 0.1-10 m/s

Q: What maintenance is required for flow sensor probes?

Regular cleaning to prevent fouling, calibration checks every 6-12 months, inspection for corrosion or coating buildup, and verification of electrical connections and grounding.

Q: How do I select the right flow probe for my application?

Consider fluid properties (conductivity, viscosity, temperature), flow range, pipe size, required accuracy, pressure conditions, and compatibility with existing control systems.

Q: Can flow probes handle aggressive chemicals?

Yes, with proper material selection (PTFE lining, Hastelloy electrodes) and chemical compatibility verification according to ISO 2812 standards.

Component Specifications

Definition

A sensor element or probe is the primary detection component within a flow sensor that directly interacts with the fluid medium to measure flow rate, velocity, or volume. It converts physical flow parameters into electrical signals through various transduction mechanisms, enabling real-time monitoring and control in industrial systems.

Working Principle

Operates based on electromagnetic induction (Faraday's Law), ultrasonic time-of-flight, thermal dispersion (heat transfer), or differential pressure (Bernoulli's principle) to detect fluid flow characteristics without moving parts in most designs.

Materials

316L stainless steel housing, PTFE/PFA lining, ceramic or polyurethane sensing surfaces, gold-plated electrodes, epoxy encapsulation, with IP67/IP68 protection ratings.
