Belimo FM500-250 : Ultrasonic Flow Sensor, ANSI 250 Flanged 5" Inch, 5.94 to 594 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
