210 Series Ultrasonic BTU (M-bus)
The ultrasonic heat meter (UHM )is a highly accurate and stable heat meter. It utilizes ultrasonic technology to measure household heating and cooling energy consumption. This meter is a compact meter that has been designed to incorporate the flow sensor and calculator all in one unit for simplification of the unit’s installation. The 8-digit LED display makes reading the measured value simple and easy. The compact size and lack of moving parts makes the series UHM a low maintenance unit. These features make it great for installation on chillers, and boilers.
● Flow Direction: Unidirectional
● Enclosure Rating: IP65
● Process Connection: See chart
● Mounting Orientation: Horizontal or Vertical
● Agency Approvals: CE
FEATURES
● Works with both heating and cooling systems
● High accuracy
The high quality ultrasonic transducer and advanced electronic measurement technology work together to ensure the meter's high accuracy and stability.
● No moving parts
This decreases the maintenance cost and ensures that the meter is resistant to dirty water.
● PT1000 platinum resistance
● Low starting flow-rate
The U-shaped acoustic path widens the dynamic flow-rate measurement range and increases the accuracy of low and high end measurements where other, more narrow ranged, devices are inaccurate.
● Horizontal or vertical installation
● M-BUS output ports can be used for automated meter reading.
● Automatic diagnostic function
An error code will be displayed on the screen to indicate the problem.
● Ability to install an 3.6 V battery that can last up to 6 years.
