Component Specifications

Definition
A flow sensor element is the core sensing component within flow meters and load cells that converts fluid flow parameters into measurable electrical or mechanical signals. It operates based on specific physical principles to provide accurate flow rate data for process control, monitoring, and automation applications in industrial settings.
Working Principle
Operates on principles such as differential pressure (using orifice plates or venturi tubes), thermal dispersion (measuring heat transfer from heated elements), electromagnetic induction (Faraday's law for conductive fluids), ultrasonic transit-time or Doppler effect, or Coriolis force (measuring mass flow through tube vibration). The element detects changes in flow characteristics and generates proportional output signals.
Materials
Stainless steel (316L, 304), Hastelloy, titanium, ceramic (alumina), PTFE, polypropylene, or specialized alloys depending on fluid compatibility. Sensing surfaces may use platinum RTD elements, piezoelectric crystals, or electromagnetic coils with protective coatings.
Technical Parameters
  • Accuracy ±0.5% to ±2% of reading
  • Flow Range 0.1-1000 L/min
  • Output Signal 4-20 mA, 0-10V, pulse, or digital protocols
  • Response Time <100 ms
  • Pressure Rating Up to 100 bar
  • Temperature Range -40°C to 150°C
  • Process Connection G1/2", 1/2" NPT, flange DN25
Standards
ISO 5167, DIN EN 60529, ISO 4064

Frequently Asked Questions

What is the difference between a flow sensor element and a complete flow meter?

The flow sensor element is the core sensing component that detects flow, while a complete flow meter includes additional electronics, housing, display, and connectivity for signal processing and output.

How do I select the right flow sensor element for my application?

Consider fluid type (liquid/gas, viscosity, conductivity), flow range, pressure/temperature conditions, required accuracy, material compatibility, and output signal requirements. Consult manufacturer specifications and industry standards.

What maintenance do flow sensor elements require?

Regular calibration checks, cleaning to prevent fouling or buildup, inspection for corrosion or damage, and verification of electrical connections. Some elements may require periodic replacement based on operating hours or exposure to aggressive media.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
