Application

MULTICAL® 403 is a static heat meter, cooling meter or combined heat/cooling meter based on the ultrasonic principle.

The meter is intended for energy measurement in almost all types of thermal installations where water is used as the energy-conveying medium.

MULTICAL® 403 consists of a calculator, a flow sensor and two temperature sensors. MULTICAL® 403 has been developed for measurement of energy consumption in flats, single-family and multi-family houses, housing associations, blocks of flats and small industry. The meter is simple to install, and it has a temperature range of 2 ...180 °C and a meter programme with nominal flow from q p to 15 m³/h.

0.6 m³/h

Robust and accurate

Due to its robust design and high quality MULTICAL® 403 is practically maintenance free, and its simple set-up makes it easy to configure via the meter's front keys.

MULTICAL® 403 has been optimised compared to earlier generations. The total dynamic range has been increased to 1600:1 from saturation to start up and the meter has an approved dynamic range of 250:1. It is thereby secured that every conceivable consumption is measured with the same well-known Kamstrup precision.

2

The meter can be powered by mains or battery supply as required. You can choose between a small battery without transport restrictions or a more powerful battery with 16 years’ lifetime. No matter which solution you choose the power consumption of MULTICAL® 403 is low.

Functionality

Volume is measured using bidirectional ultrasonic technique based on the transit time method, proven a long-term stable and accurate measuring principle.

Accumulated heat energy and/or cooling energy can be displayed in kWh, MWh or GJ, all in the form of seven or eight significant digits. The display has been specially designed with a view to obtaining longevity.

A wide range of parameters are configurable via the front keys of MULTICAL® 403: Flow sensor position in inlet or outlet, energy unit, primary M-Bus address, radio on/off, target dates etc. Configuration can be carried out on site, thus contributing to a reduction of stocks and installation time.

MULTICAL® 403 is available with communication modules for

Wireless M-Bus, M-Bus and RS232. The modules are available with either pulse inputs or pulse outputs. In addition to reading current values, the programmable data loggers of

MULTICAL® 403 can be read via M-Bus.

MULTICAL® 403

Energy calculation

MULTICAL® 403 calculates energy on the basis of the formula stated in EN 1434-1, which uses the international temperature scale issued in 1990 ®ITS-90 and the pressure definition of 16 bar. In a simplified form the energy calculation can be expressed as:

Energy = V x ∆

Θ x k.

V is the added volume of water

Θ is the measured temperature difference k is the heat coefficient of the water

The calculator always calculates energy in [Wh], which are subsequently converted into the selected measuring unit.

E [Wh] =

E [kWh] =

E [MWh] =

E [GJ] =

V x

∆Θ x k x 1000

E [Wh] / 1,000

E [Wh] / 1,000,000

E [Wh] / 277,800

MULTICAL® 403 operates with a number of different energy registers. All energy types are data logged and can be displayed according to configuration. Both in the display and during data reading each energy type is uniquely defined. The energies are calculated as follows:

E1 = V1 x (t1-t2) x k

E3 = V1 x (t2-t1) x k

E8 = V1 x t1

E9 = V1 x t2

A1 = V1 x (t5-t2) x k t2

A2 = V1 x (t2-t5) x k t2

MULTICAL® 403

Calculator functions

Pulse inputs A and B

MULTICAL® 403 has two extra pulse inputs (A and B), which are placed on selected communication modules. The pulse inputs are used for acquisition and remote accumulation of pulses from e.g. mechanical water meters and electricity meters. The pulse inputs function independently of the meter itself. Therefore, they are not included in any energy calculations. The two pulse inputs are identically constructed and can be individually set up to receive pulses from water meters or electricity meters.

Pulse outputs C and D

MULTICAL® 403 has two extra pulse outputs (C and D), which are placed on selected communication modules. The pulse outputs provide output from selected counter registers determined by the country code. As the meter has two pulse outputs, it is possible to provide output from two of the following counter registers via pulse outputs C and D respectively:

• E1 (Heat energy)

• E3 (Cooling energy)

• V1 (Volume)

Note: As selected counter registers are configured by the country code, the configuration cannot be changed after delivery.

Pulse outputs are by default configured for the following registers:

The resolutions of pulse outputs always follow the least significant digit in the display, which is determined by the CCC-code e.g. at CCC=119: 1 pulse/kWh and 1 pulse/0.01 m³.

Data logger

MULTICAL ® 403 has a permanent memory (EEPROM), in which the results from various data loggers are saved. The data logger is programmable. The required data logger profile is selected via the RR-code of the configuration number. Unless otherwise stated by the customer the RR-code is set at 10, which is the default data logger profile. This default data logger profile logs the same data logger registers as MULTICAL® 602, but the logging depth is wider (see table below). Both data logger registers and logging depths are programmable, and individual logging profiles can be prepared as required by the customer. Please contact Kamstrup for further details.

The default data logger profile (RR-code = 10) includes the following six data loggers with allocated depths:

Integration mode

MULTICAL® 403 uses time-based integration, which means that calculations of accumulated volume and energy are carried out at fixed time intervals. The time interval is configurable via the L-code and is independent of the water flow. Please be aware that choice of integration mode in combination with selected power supply defines the meter’s battery lifetime.

The meter has six optional integration modes; three modes, in which the meter's display remains switched on and three modes, in which the meter’s display is switched off 4 min. after the latest registered activation of a front key. During periods with the display switched off a dot flashes (heart beat indication) at intervals of 30 seconds to indicate that the meter is active.

Adaptive mode (4-64 s)

Adaptive mode is the meter’s intelligent integration mode, in which the time interval is continuously adjusted. This mode combines the long battery lifetime obtained in Normal mode with the high measuring and calculation resolution obtained in Fast mode.

Thus, in adaptive mode MULTICAL® 403 measures at high resolution during periods with changes in the system requiring accurate measurements and saves battery power during stable periods.

Adaptive mode is recommended for all systems including those with tap water exchanger.

Normal mode (32 s)

In normal mode the integration interval is set at 32 seconds, which means that the meter calculates accumulated volume and energy every 32 seconds.

Normal mode is recommended for systems with hot water tank and similar systems.

Fast mode (4 s)

In fast mode the integration interval is set at 4 seconds, which means that the meter calculates accumulated volume and energy every 4 seconds. Fast mode is recommended for all systems including those with tap water exchanger.

Tariffs

MULTICAL® 403 has 3 extra tariff registers TA2, TA3 and TA4, which can accumulate heat energy or cooling energy (EE=20 accumulates volume) parallel with the main register based on preprogrammed tariff conditions (to be included in the order). Irrespective of the selected tariff type, the tariff registers are named TA2, TA3 and TA4 in the display.

As the main register is considered the legal billing register, it is accumulated no matter the selected tariff function. Tariff conditions TL2, TL3 and TL4 are monitored at every integration.

If the tariff conditions are fulfilled, consumed heat energy, cooling energy or volume is accumulated in either TA2, TA3 or TA4 parallel with the main register.

MULTICAL® 403

Calculator functions

Coefficient of performance (CP) of a heat pump

In houses with heat pumps with single output it is expedient to measure both the released thermal energy and the gained electrical energy, based on which the coefficient of performance (COP or CP) can be calculated. COP is the abbreviation of ”Coefficient Of Performance”.

The calculation is based on simple proportional numbers between calculated thermal energy

(E1) and electrical energy, which is measured via pulse input B (Input B):

CP=

Thermal energy [E1]

Electrical energy [Input B]

Electrical energy (Input B) is always registered in kWh, whereas thermal energy (E1) is either registered in kWh, MWh or in GJ depending on the selected B-code. No matter which unit you choose the meter calculates CP correctly. The CP value is displayed with one decimal and is a value in the interval 0.0…19.9.

CP can also be used for measurement in gas-fired systems, CP being expressed as kWh/Nm³ gas.

Configurable M-Bus modules

In the module bay of MULTICAL® 403 a communication module can be mounted, adapting the meter to various applications. The M-Bus module is powered through the M-Bus network and is thus independent of the meter’s internal supply. Two-way communication between M-Bus and energy meter is carried out via a digital isolator providing galvanic separation between

M-Bus and meter. The module supports both primary, secondary and enhanced secondary addressing. The module can communicate at communication speeds of 300, 2400, 9600 or

19200 baud and automatically detects the speed used.

The output data package can be configured to include various register combinations by means of the programs METERTOOL HCW and READy Manager.

The module can be read at intervals of 10 seconds without the battery lifetime being influenced.

Info codes

MULTICAL® 403 constantly monitors a number of important functions. If a serious error occurs in measuring system or installation, a flashing “INFO” will appear in the display. The ”INFO” field keeps flashing as long as the error is present no matter which reading you choose. The

”INFO”-field is automatically switched off when the error has been corrected.

In addition to the ”INFO”-field the current info code can be displayed. In MULTICAL® 403 each digit of the info code is dedicated to one of the meter’s elements. The below table shows the info code structure together with an example of the info code.

By means of the meter’s primary key you can choose from and switch between the meter’s four display loops. When delivered the meter is in transport state, which means that USER,

TECH and SETUP loops are available. Depending on country code, SETUP loop can be locked in transport state and is thereby not available on delivery. TEST loop can only be accessed if the test seal is broken.

The meter’s four display loops are intended for four different usage situations.

USER loop

The meter’s configurable display loop, which is intended for the user. The readings in this loop can be adjusted to the user’s requirements via the DDD-code.

TECH loop

This loop is intended for technicians and is not configurable. In this loop all the meter’s readings are shown. The loop comprises readings such as serial number, date, time, config no., software revision, segment test. TECH loop also comprises a number of fixed module readings as well as a number of module readings, which depend on the module.

SETUP loop

This loop is intended for the technician too. In this loop the technician can configure the meter via the front keys. In general (unless otherwise informed by the customer) the loop is open in transport state. When the first integration has been carried out by the meter, SETUP loop is locked and it is no longer possible to access SETUP loop unless the installation seal is broken.

TEST loop

Used by certified laboratories for reverification of the meter. This loop is not available unless the meter’s test seal is broken.
