Dust Control Devices and Spray Heads

Dust Control Device SprayheadFM200 Multi-Application Flow Monitor
The FM200 Multi-Application Flow Monitor is a highly effective dust control and flow monitoring device designed to detect FLOW / NO FLOW conditions in pipes, chutes, spouting systems, and material handling processes.
Using a unique ultrasonic sensing technology, the FM200 monitors the movement of materials through a system without requiring direct contact with the material stream. This advanced sensing method makes the FM200 a versatile solution for a wide range of industrial environments where reliable flow detection is critical.
Whether monitoring air, liquids, powders, or granular materials, the FM200 provides dependable detection that helps operators maintain proper system performance, reduce equipment downtime, and ensure dust control systems operate efficiently.
The FM200’s flexible design and advanced sensing capabilities allow it to exceed typical industry standards for flow monitoring applications.

Key Features

Control Unit

The FM200 control unit continuously monitors the movement of materials through pipes, chutes, and spouting systems to ensure proper flow conditions are maintained.
Capabilities include:

  • Detects movement of air, liquids, and solid materials through process systems
  • Senses both the presence and absence of material flow within air streams
  • Compatible with pipe or chute systems ranging from ½ inch to 60 inches or larger in diameter

To accommodate different operating environments and materials, the FM200 offers three user-selectable sensitivity ranges:

  • Low
  • Medium
  • High

Control Outputs

The FM200 control unit offers multiple output options to integrate with existing control and monitoring systems.

Relay Contacts

  • Normally Open (N.O.) and Normally Closed (N.C.)
  • Rated for 4 Amps at 125/250 VAC

TTL Output

  • 0–5 Volt signal

RS232 Output

  • Low/High output communication capability

These output options allow the FM200 to interface with a variety of automation, alarm, or process control systems.

FM200 Sensor for Dust Control

LED Status Indicators

The system provides clear visual indicators for operating conditions.

  • Green LED: Flow detected
  • Red LED: No flow detected

These indicators allow operators to quickly verify system status at a glance.


Control Unit Housing

The control unit is housed in a durable polycarbonate enclosure designed for industrial environments.
Housing Specifications:

  • Dimensions: 5″ x 7″ x 3″ (125mm x 175mm x 75mm)
  • Integrated conduit knockouts for simplified wiring
  • Designed for reliable operation in demanding industrial settings

Flow Sensor

The FM200 flow sensor mounts externally on the outside of the pipe or chute, eliminating the need to penetrate the process line or disrupt material flow.

Sensor Features

  • External mounting design for quick and easy installation
  • Built-in mounting tabs for secure placement
  • Pre-wired with 6 feet of 18 AWG two-conductor cable
  • Low-voltage operation: 5 VDC, 200 mA maximum

Three sensor styles are available to accommodate different pipe sizes and installation environments.


Easy Installation. Reliable Operation.

The FM200 is designed for simple installation and long-term reliability.
Because the system contains no moving parts, it requires no routine maintenance, making it an ideal solution for continuous industrial monitoring.
With its flexible configuration options and robust sensing technology, the FM200 provides a dependable way to monitor flow conditions and support effective dust control system performance.
