FL 204 Four Wire Turbine Flow Meter

The Electronet FL-204 is a robust four-wire turbine flow transmitter designed for precise flow measurement in a wide range of industrial applications. Its simple, cost-effective construction and high-performance magnetic sensing technology make it ideal for both conductive and non-conductive liquids. With an LED display, flexible output options, and IP-67 / Flameproof protection, the FL-204 ensures reliable operation even in harsh environments.

• 4-wire system for stable and accurate signal transmission

• Simple and cost-effective construction

• Suitable for conductive and non-conductive liquids

• Bright LED display for flow rate (4 digits) and totalized flow (8 digits)

• Batch / High / Low relay output options

• Integral or remote electronics configuration

• Low maintenance with durable construction

• Weatherproof IP-67 & Flameproof (CMRI IIA IIB) certified electronics

The flowing liquid rotates a vaned rotor inside the pipe. A magnetic pickup coil senses the rotor's angular velocity and converts it into a pulsating electrical signal.

• The signal frequency is directly proportional to the flow rate.

• The transmitter converts this into a linear 4–20 mA output for process control.

• Total flow is obtained by summing the pulse signals.
