220 Series BTU Meter is designed for long distance installation. It solved the problem of long distance wiring between Calculator and Flow Sensor. The meter adopts good-quality piezoelectric ceramic transducer to ensure high precision and stability.

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

· RS485 and 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 optional 3.6 V battery that can last up to 6 years
