Equipment for Pumping Tests on Boreholes and Wells

The well and borehole pumping test system is used to automatically perform hydrodynamic pumping and head rise tests to verify the yield of drilled wells. The system allows for long-term autonomous operation without the need for an operator to be present at the equipment. The control and data-logging unit continuously measures the water level in the well using a submersible sensor and regulates the pump speed via a variable-frequency drive. This makes it possible to maintain a constant, preset flow rate regardless of the current water level, or conversely, to regulate the flow rate so that a constant water level is maintained. The measured water level and flow rate values are stored in the device’s memory and, at set intervals, are transmitted via GSM/GPRS data transfer to a server for archiving, display, and further processing.

Description

The basic configuration consists of a control panel with an H3-G-TB3 control unit, a frequency converter, and control elements for both manual and automatic operation, a FLODIS water meter with a CYBLE NF 001 inductive speed sensor, and a TSH37 submersible level sensor.
The system can operate in automatic or manual mode. The measured data is displayed on the measuring station’s color graphic touchscreen, which is also used to configure and control the system.
In automatic mode, the system regulates the pump speed based on the required flow rate or water level. The measured data is transmitted via GSM/GPRS to a server, where it is accessible through a standard web browser on a PC or mobile phone.
The measurement range of the level sensor, cable length, and water meter type can be customized according to the customer’s requirements when placing an order. The system can also be expanded to include additional sensors for measuring water quality parameters.
