The Danfoss SonoMeter 30 is a range of
ultrasonic, compact energy meters intended for
measuring energy consumption in heating and
cooling applications for billing purposes. The
meters are designed for remote meter read-out
(AMR).
SonoMeter 30 energy meters consist of
an ultrasonic flow sensor, a pair of Pt500
temperature sensors and a calculator
with integrated circuits for temperature
measurement, flow calculation and energy
calculation.

• No calming sections needed before or after the
flow sensor (DN 15-DN 50)
• For DN 65 to DN 100 calming sections are
needed (5 x DN on inlet and 3 × DN on outlet of
flow sensor)
• Remote reading via M-Bus, radio OMS 868 Mhz,
RS 485 Modbus, BACnet, pulse output or optial
interface
• Two pulse inputs or outputs as standard
(default delivered as pulse output - can be
changed)
Optical interface
Optical interface is integrated into the front panel of the calculator. It is designed for data reading
via M-bus protocol and parameterization of the meter using SonoMeter 30 UserConfig software and
optical head OG-1-USB.
The optical interface is activated by pressing the control button and shuts automatically off 5 minutes
after the last pressing button or after completing data transmission via interface.
Wired M-Bus interface
The energy meter has 1 slot for an additional communication module. The internal M-Bus module
provides data reading possibility via M-Bus protocol:
• M-Bus protocol according to EN13757-3 standard
• 2-wire with polarity reversal protection
• Electrical isolation
• •Maximum voltage 50 V DC
• Current drawn: one M-Bus load (1.5 mA)
• Primary or secondary addressing
• Baud rate 2400 bps
• Battery lifetime min. 11 years (2 AA cell)
• Battery supply communication is limited on every 15 min at 2400 baud rate or faster, 70 meters
on bus
• Fastest reading interval at mains supply: no limits
Radio OMS 868.95 MHz interface
• The module can provide data reading via radio module:
• Wireless M-Bus protocol according to EN13757-4
• OMS (open metering system) compatible, compliant to OMS 4.0.2
• T1 mode (unidirectional)
• Sending interval every 90 seconds (suitable for ‘walk by’ readings)
Modbus RS-485 module
RS-485 module is Modbus RTU protocol and a serial interface for communication with external
devices.
2 pulse inputs or 2 pulse outputs (set up by jumpers)
There is a connector J on the calculator plate between the temperature sensors and pulse input /
output connection terminals. By means of connecting or opening the connector contacts, the pulse
inputs or outputs are activated.
Note: On delivery the heat meter is configured with two outputs.

Power supply (one of following depending on meter configuration):
• 2 AA cell battery 3.6 V DC, 2.4 Ah (Li-SOCl2) lithium battery, life time at least 11 years
• Mains power supply 12 V AC to 36 V AC (50/60 Hz) or 12 V DC to 42 V DC:
- The mains power supply 24V AC/DC module is mounted inside in the meter
- Consumption is max 20 mA
- Galvanically isolated + internal backup battery size AA cell, 3.6 V, 2.4 Ah, lithium battery (LiSOCl2). When the external power supply is turned off, the battery life time is not less than 11 years
(without data reading via a digital interface)
• Mains power supply 230 V AC (+10% / -30%) 50/60Hz:
- The meter should be equipped with an internal power supply unit and an external transformer.
The 230 V AC to 24 V AC transformer is used for connection to mains power supply 24 V AC/DC
module inside the meter
