380 Btu Meter series
gas, for liquids
with temperature measurement
BADGER METER 380 Series Btu System is basically an all-in-one energy usage package for monitoring hydronic heating or cooling systems. The main advantage of the Series 380 Btu meters is cost saving, integrated flow and temperature sensors, commissioning via computer connection, PEEK flow sensor, rugged design, two temperature probes, easy installation etc.
One temperature probe is mounted directly in the flow sensor tee and on supply or the return line. This setup includes energy measurement units, measurement method, communication protocol, pulse output control, fluid density and specific heat parameters.
The unit uses a 12-28 VAC input power and promises an accuracy of ± 2% of flow rate within flow range & ± 0.5% repeatability. The housing is made of polycarbonate with PEEK flow sensors, polyurethane potting material and brass made tee material. The sensor body is available in sizes: 3/4”, 1”, 1 1/4”, 1 1/2”and 2”. The operating temperature range between -20°C to 65°C and RTD meets IEC751 Class B.
