Belimo FM250-250 : Ultrasonic Flow Sensor, ANSI 250 Flanged 2-1/2" Inch, 1.52 to 152 Flow (GPM), 0-10V Output Signal, IP54 NEMA 2, 5-Year Warranty

Belimo FM250-250 : Ultrasonic Flow Sensor, ANSI 250 Flanged 2-1/2" Inch, 1.52 to 152 Flow (GPM), 0-10V Output Signal, IP54 NEMA 2, 5-Year Warranty

This ultrasonic flow sensor offers precise measurement of water flow in closed heating and cooling systems, even with the presence of dirt, magnetite, or glycol.

Key Features:

• Accurate and Reliable:
  • Calibrated for temperature and glycol concentration to minimize errors.
  • Multi-point wet calibration ensures exceptional accuracy.
  • Calibration certificate included
• Durable Design:
  • Withstands harsh conditions with robust construction.
  • Low pressure drop for minimal impact on system performance.
• Maintenance-Free:
  • No moving parts means long operation lifespan and reduced maintenance costs.
• Easy to Use:
  • DC 0.5...10 V output signal for seamless integration with monitoring systems.
  • Compact design for flexible installation.

How it Works:

The sensor uses ultrasonic waves to measure flow velocity and calculates the volumetric flow rate. A built-in temperature sensor compensates for temperature variations, while automatic glycol compensation corrects for the effects of glycol mixtures in the coolant. This combination minimizes errors and ensures accurate flow measurement.

Benefits:

• Improved system efficiency through precise flow monitoring.
• Reduced maintenance costs due to durable, maintenance-free design.
• Reliable performance even in challenging environments with dirt, magnetite or glycol.
• Patented automatic glycol compensation
• High repeatability
