For low pressure injections, DAT instruments provides two kinds of products:
JET AME 4000 / I, up to 4 pumps, with monitoring, recording and automation functions;
JET DSP 100 / IR, for one single pump, with displaying and recording functions;
JET 4000 AME / I (from 1 to 4 pumps):
Measuring and recording of pressure, flow and volume parameters of cement grout.
Display, directly on datalogger LCD, of instantaneous pressure, flow rate and volume values.
Display in real time of injection graphics and of summarizing reports.
Automatic stop of the injector when maximum established pressure, maximum volume of the grout are reached, via GIN method or when achieving maximum duration.
Automatic restart of pumping if, after being stopped, pressure goes under pre-established value.
Start of the injectors directly from JET 4000 AME / I datalogger keyboard.
Sending from a PC of a project with different kind of pile and valve in order to avoid set up in field.
Data downloading to PC, in order to create and print summarizing reports, to obtain easy and quick information files concerning injections carried out and to export data to Microsoft Excel.
Possibility to print data immediately, via JET PRINT60 printer which can be installed into the datalogger.
JET DSP 100 / IR (1 pump):
Measuring and recording of pressure, flow and volume parameters of cement grout.
Display with very big digits, directly on datalogger LCD, of instantaneous pressure, flow rate and volume values.
Data downloading to PC, in order to create and print summarizing reports, to obtain easy and quick information files concerning injections carried out and to export data to Microsoft Excel.
Solutions
(1) In the first case, the pole was carried out well, with the use of the datalogger JET 4000 AME / I: all valves were injected with the correct amount and pressure of cement.
(2) Badly made pole, at the expense of its lift: some valves did not open, perhaps because of low pressure or because of the carelessness of the operator.
(3) Poorly made pole, to the detriment of its lift: some valves have a lower cement quantity than the project specification.
DAT INSTRUMENTS solution:
The JET 4000 AME / I datalogger:
Controls the injector during the execution of the valves, automating the start and shutdown of the pump;
measuring pressure, flow and volume of cement, as well as date and time of work;
provide detailed reports of the quality of work, easily accessible and usable;
contains the project with the specifications of the poles to be realized, valve for valve, without the need to set the data directly on site.
