1000 – Ultrasonic heat meter
Design and function The SONOMETER™1000 as a compact heat meter
consists of the following components:
- Ultrasonic flow sensor;
- Calculator with integral hardware and software
for measuring flow rate, temperature and
energy consumption;
- Temperature sensors.
Calculator
The calculator contains all the necessary circuits
for recording the flow rate and temperature and
for calculating, logging and displaying the data.
The calculator housing can be mounted directly
on the flow sensor or on the wall. The heat
meter can be conveniently read from a single-
line 7-digit display with units and symbols. A
push-button provides user-friendly control of
the various display loops. All failures and faults
are recorded automatically and shown on the
LC display. To protect the reading data, all the
relevant data are saved in a non-volatile memory
(EEPROM). This memory saves the measured
values, device parameters and types of error at
regular intervals.
Ultrasonic flow sensor
The ultrasonic technology of the flow sensor
permits very high measuring accuracy and can
be used in the supply or return line. The flow
sensor meets the requirements of EN 1434 / class
2 and 3. The standard cable length between the
calculator and the flow sensor is 1.5 m (optional
5 m).
Supply voltage:
- Lithium battery 3.0 V DC (12-year life)
- Lithium battery 3.6 V DC (16-year life– optional)
- Mains unit 230 V AC or 24 V AC
Temperature Sensors
Pairs of Pt 500 temperature sensors with 2-wire
leads are used.
Interfaces
The SONOMETER™1000 is equipped as standard
with a ZVEI optical interface with the M-Bus
protocol as per EN 1434. This interface is used,
for example, for communication with the
HYDRO-SET parameterization software. The
heat meter is equipped with two slots, one slot
for communication, the second slot for pulse
modules.
The following communication modules are
available as options:
- Real Data Radio module
- M-Bus module to EN 1434
- RS 232 module
The RS 232 module is a serial interface and
permits data exchange with the heat meter.
The Radio module communicates a list of
predefined data records. This can be edited by
HYDRO-SET.
Pulse Input
Two additional pulse inputs are available. The
pulse value and the unit is configurable for heat,
water, gas or electrical meter by HYDRO-SET.
Also two accounting day’s are available for both
inputs.
Pulse Output
The heat meter provides levels for two optional
external pulse outputs, which can be freely
programmed using the HYDRO-SET software.
Possible pulse output values
- Energy
- Volume
- Tariff energy 1
- Tariff energy 2
- Tariff condition 1, limit switch
- Tariff condition 2, limit switch
- Energy error
- Volume error
Module combinations
The following module combinations for data
transmission are available ex works or for
retrofitting in the field (two slots):
- Pulse input module
- Pulse output module
- Pulse input module and pulse output module
- Communication modules:
- M-Bus or
- RS 232 or
- radio
- In combination with
- pulse output module
- pulse input module
Event Memory
- Events such as changes and faults are stored in
a non-volatile memory with a capacity of up to
31 entries. The following events are recorded:
- Checksum error
- Temperature measurement error
- Ultrasonic echo time measurement errors
- Start and end of test mode
Monthly Memory
The SONOMETER™1000 has a history memory of
24 months. The following values are stored in the
EEPROM on the programmed date 1 … 31 of the
actual month:
- Date/ Time
- Energy
- Tariff energy 1
- Tariff energy 2
- Tariff definition 1
- Tariff definition 2
- Impulse counter 1
- Volume
- Error day counter
- Maximum monthly flow rate
- Maximum monthly power
- Date of maximum monthly flow rate
- Date of maximum monthly power
- Impulse counter 2
