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
