Explore the technical data and configuration possibilities of the EconomyLine for your cost-optimized level measurement.
EconomyLine

Proven Quality at Attractive Price
These cost-effective level measurement devices use proven types from SmartLine 50 and StandardLine 6 with reduced option scope. For visual level indication on containers with water or oil at low pressures and temperatures, the most complex solution is not always required.
EN and ANSI flanges are included as standard, however in three specified nominal sizes as loose flange combinations. This proven solution from vessel and shipbuilding compensates for manufacturing tolerances. Simplified pressure-temperature diagrams reduce testing effort and protect manufacturing costs with PED-compliant design.
Magnetic switches and transmitters for electrical signal transmission to control systems can optionally be added. Shipbuilding approvals from the largest classification societies significantly expand application possibilities.
