Description
WLT-1 is a functional tool to measure and record the depth of water (liquid) in a location. Data measurement results can then be displayed on a computer screen in the form of charts and tabulation.
This tool is equipped with Telemetry system, ie a system that allows users to obtain data from these instruments should do not have to go to the installation location.
This tool uses the pressure sensor (pressure transducer) that changes the water level changes to changes in water pressure which in turn translated into numbers height / depth of the water level. The data rate is then stored in memory with time interval data storage can be arranged.
The data has been stored on the device can be taken in several ways, namely:

The data has been stored on the device can be taken in several ways, namely:
- Retrieving data directly using a computer (laptop) is connected directly to the device via serial port 232 provided
- Taken (monitors) remote data (telemetry), which is using some of the following ways:
SMS
- Request data and the final status of the device Automatic Data Report, which is sending data to the user automatically by sending a time interval set.
- Early warning of the tool if the water level beyond the limits specified (Alert level) as well as warning of critical conditions on the power supply (Power Alert).
- Provides command (command) to the instrument in terms of changing the parameter settings of the device.
CSD / HSCSD
Delivery of streaming data. Some or all of the data already stored in memory is sent at one time. To use this facility the user must have the Central Unit * or dial-up connection that has facilities CSD / HSCSD as well as GSM Modem KENDA software Aquisition Data System (optional).
GPRS
GPRS
Equipment will always be connected to the Internet to provide data to the server continuously KENDA, so users can monitor the device data via the Internet must have a device not necessarily Central Unit. In addition this tool can also send data via e-mail to the user.
Applications
Monitor wells
River
Dam
Tank Water / Oil

Software
KENDA Data Aquisition Software, a software to facilitate users in data retrieval (via dial-up CSD / CSHD) and data processing that appears in the form of graphs and tables. The data can then be printed on paper. This software can be operated in Windows 98/ME/XP.
The minimum computer specifications needed: 512MB RAM, 1GB Hardisk space, serial RS-232 port.
Is an example of graph data from instruments WLT-1 in one major industry in east Java. Data the show is the data on October 24 s / d November 5, 2008 with the positions of positive water level in the
above the ground (well artesis). Dengansampling at set intervals every 30 minutes, the data generated graphics are very good that the graph can be known when the decline in water level each day, the maximum value, minimum and average water level.
