MULTICAL
401 constantly checks a series of vital functions, whereby serious system errors can be detected.
Should one or several serious errors occur in the energy meter, the display will show an «E» at the left side. In
case of short-duration errors the «E» will only be displayed as long as the error exists. If an error situation has
existed for more than and hour, the information code will be permanent and can now only be deleted by opening
the meter (see section 7.5 Reset functions ).
When the first permanent information code occurs, it is stored in the EEPROM together with the date and the
energy and volume registers at the time the error occured.
The meter’s actual «info code» appears from the last display indication in the main menu, i.e. when the front key
has been activated 4-10 times depending on the selected display configuration. During normal operation the
meter shows «000 info».
If one or more of below errors occur, the sum of the information codes is shown. E.g. a simultaneous error in both
temperature sensors is shown as «012 info».

These information codes occur during transport below freezing point as well as during storage.
During installation the info codes are reset as described in section 7.5 Reset functions .
2)
Info code 128 is only active when the meter is ordered with a battery (type number 66-Wx-2xx-xxx).
Use METERTOOL (see section 14) for reprogramming.

Page 35: Temperature Measurement
® TECHNICAL DESCRIPTION MULTICAL Temperature measurement The temperatures in flow and return are measured by an accurately matched Pt500 and Pt100 sensors. During each temperature measurement MULTICALÒ 401 sends a measuring current through each sensor, approx. 0.5 mA for Pt500 and 3.0 mA for Pt100. 2 measurements are made to suppress any 50 Hz ripple collected via the sensor cables.

Page 36: The Flow Part
Manufacturers of flow sensors have been working with alternative techniques to replace the mechanical principle. Research and development at Kamstrup have proven that ultrasonic measuring is the most viable solution. Combined with microprocessor technology and piezoceramics, ultrasonic measuring is not only accurate but also reliable.

401 constantly checks a series of vital functions, whereby serious system errors can be detected.
Should one or several serious errors occur in the energy meter, the display will show an «E» at the left side. In
case of short-duration errors the «E» will only be displayed as long as the error exists. If an error situation has
existed for more than and hour, the information code will be permanent and can now only be deleted by opening
the meter (see section 7.5 Reset functions ).
When the first permanent information code occurs, it is stored in the EEPROM together with the date and the
energy and volume registers at the time the error occured.
The meter’s actual «info code» appears from the last display indication in the main menu, i.e. when the front key
has been activated 4-10 times depending on the selected display configuration. During normal operation the
meter shows «000 info».
If one or more of below errors occur, the sum of the information codes is shown. E.g. a simultaneous error in both

No errors found
+002
The information code indicating flow sensor error is activated when the water flow has
continously been below cut-off for 48 hours, while Δ t has been > 20 K
1)
+004
The return sensor does not comply with its measuring range 0…165°C. The sensor can be
short-circuited or disconnected.
1)
+008
The flow sensor does not comply with its measuring range 0…165°C. The sensor can be short-
circuited or disconnected.
1)
+016
Air is detected in the flow sensor (is only indicated as long as the error exists)
2)
+128
The battery must be replaced. This code occurs 12 years after the hour counter was reset.
1)
These information codes occur during transport below freezing point as well as during storage.
During installation the info codes are reset as described in section 7.5 Reset functions .
2)
Info code 128 is only active when the meter is ordered with a battery (type number 66-Wx-2xx-xxx).
Use METERTOOL (see section 14) for reprogramming.

Для измерения и регистрации параметров теплоносителя (расхода, объема, массы, температуры, давления, их средних и итоговых значений), времени работы и количества (тепловой энергии) при контроле и учете, в том числе коммерческом, в водяных системах те…
Снят с производства 1 января 2011 года.
Компактный ультразвуковой теплосчетчик предназначен для объектов с небольшим потреблением тепловой энергии, где не требуется почасовая регистрация параметров теплоносителя: квартиры, коттеджи, встроенные помещения многоквартирных домов – магазины, аптеки, офисы.
Вся электроника прибора размещена на одной печатной плате в корпусе вычислителя, что обеспечивает низкую цену, высокую надежность, простоту обслуживания и стабильность метрологических характеристик на протяжении всего срока службы.
Вычислитель можно разместить как на расходомере, так и на стене в удобном для снятия показаний месте. Один из температурных датчиков установлен в теле расходомера, другой через переходной ниппель монтируется в стандартные тройники 1/2”, 3/4″ или в шаровой кран специальной конструкции.
Номинальные расходы: 0,6 ; 1,5; 3; 3,5 [м3/ч].
Питание от встроенной литиевой батареи или от сети ~220В или ~/24В.
Помесячный архив за 32 месяца.
Для организации дистанционного сбора данных имеются встраиваемые модули: RS 232, M-Bus, радиомодуль.
Межповерочный интервал – 4 года.
Прибор имеет систему самодиагностики, регистрирующую сбои в работе системы.
Тарифные регистры позволяют накапливать показания тепловой энергии в зависимости от задаваемых условий. MULTICAL 401 имеет два дополнительных входа для водосчетчиков с импульсным выходом, что позволяет накапливать и архивировать данные о водопотреблении объекта.
