A total of 80 Hecofill probes in combination with the NK312 level controls were sold by our French subsidiary of the CS2F business. The limit switch probes were put to use for the first time on the water. They were installed using inland vessels, which travel to Paraguay along the river on a daily basis and transport up to 3500 m3 of mineral oil from the area of Argentina to Bolivia. A high level of security is provided by using the Hectronic products, both during storage as well as when handling the environmentally hazardous liquids. The tank inventories are monitored and secured to avoid overfilling. The corresponding alarm is transmitted promptly via satellites. A solution perfectly tailored to the customer, which can be used in a customisable manner all over the world in the monitoring of liquids.
