Tank monitoring system TW-32 |
|
|
|
Welba tank monitors fulfils all statutory regulations and demands imposed by the leading dairies.
A drilling of the tank is not required!
For simultaneous monitoring of 2 tanks!
WELBA tank monitors monitor fully automatically the milk temperature, the agitator function and cleaning procedures in milk cooling tanks. An operation during the everyday business is not necessary.
WELBA tank monitors can easily be connected to milk cooling tanks of all manufacturers.The installation of temperature sensors and agitator monitors is possible without additional drillings. The agitators are electronically monitored. Complex installations of revolution sensors are not necessary. Standard batteries ensure a monitoring in case of a power failure.
WELBA tank monitors distinguish between informative and critical alarms:
- Informative alarms signal the dairy farmer an incorrect operation -> action required. Thus a deterioration of the milk quality is prevented.
- Critical alarms “DO NOT LOAD” are addressing the milk tank driver. In addition to the warning-LED an external warning light, an acoustic signalling device or a dialling device can be connected. Driver and farmer decide together, whether the milk can be loaded.
Security against manipulation or unintentional adjustment of parameters is provided by the operating concept in levels, which are password-protected separately.

The configuration software WELBA "CONSOFT" is included in the delivery for convenient programming of the controller and later data evaluation.
The software offers the following functions:
- Simple and convenient parameter setting
- Processing and display of tank monitor data
- Display and printing of data in tabular or graphic form
- Storage of tank monitor data (also in CSV format)
- Software update for adding new functions (future-proof)
- REMOTE CONTROL by Internet or GSM-modem
- SMS-alarm-message

The remote maintenance of the tank monitoring system is basically possible with three options:
- A possibly existing PC with installed Teamviewer-Software (e.g. from the robot control) is permanently connected to the tank monitoring system via a USB data cable.
- Remote maintenance is carried out via the Welba EMAIL- alarm and remote maintenance modem via internet transmission.
- Remote maintenance is carried out via the Welba SMS- and remote maintenance modem via wireless transmission. For the use a standard mobile phone card (SIM-card) with data volume is required.
|
|
For the EMAIL- or SMS-alarm the Welba SMS- alarm and remote maintenance modem ESGSM-001 is required. In the event of a fault, alarms can be automatically sent to different phone numbers or email addresses.
|
|
With the SMS modem, an SMS status query is also possible, with which the current status of the tank can be queried at any time and from any location. (With the EMAIL modem, this would be possible via remote maintenance.) |

Optionally accessories
Additional components may be required for the full range of the functions of the tank monitor. |
