Features

• The M5413x/M5414x Line Powered BTU Meter is an economical wireless BTU meter and flow sensor that is highly accurate.
• The M5413x/M5414x Line Powered BTU MeterM5413x/M5414x Line Powered BTU Meter provides a radio interface to remotely collect BTU consumption by measuring inlet temperature, outlet temperature and flow rate. A BTU is defined as the amount of energy used to raise the temperature of one pound of water by one degree Fahrenheit.
• Both the inlet temperature and outlet temperature is measured using a PT1000 thermistor. The difference between the two values is computed using a microprocessor.
• Water flow is measured using a vortex flow sensor with no moving parts.
• Radio is compatible with the H2O Degree secure wireless 2.4 GHz mesh network.
• By using a magnet, the installer can force a radio transmission and receive a LED sequence feedback on radio connectivity in real-time for ease and validation of commissioning.
• Type of packet reported:
  – Data Packet (60 minute interval default).
  – Health Packet (120 minute interval default).
• Non-volatile memory maintains last reading in the event of a power failure.
• Input Voltage 24 Volt AC. Current input 45 mA typical, 250 mA maximum.
• Operating temperature 32 Degrees F to 86 Degrees F.
• Flow Rates:
  – V1000 – 0.5-10 gpm 1/2”
  – V1001 – 2-40 gpm 1”
  – V1002 – 1.3-21 gpm 3/4”
• Pulse output: PA1 pulse output – Positive (heating) therms, PA2 pulse output – Negative (cooling) therms.
