Customer's request:
Control the use of the water load in the trucks. The customer has several water dispensers to load the tanker trucks that are in charge of cleaning the city. You want a control of who makes the supply, when and how many volume (litre, gallon, ...).
Provided solution:
A GK-7 controller is installed in each dispenser, which controls a valve and a meter. Allows use only by authorised personnel using a magnetic key. All supplies can be consulted from any PC connected to the Internet.
