Level measurement

Continuous level measurement and point level detection in liquids and bulk solids

Constant product quality, plant safety and economic efficiency - these are important aspects for any level measuring point.
Levels in liquids, pastes, bulk solids or liquefied gases are often measured in tanks, silos or movable containers. For continuous, interface and density measurement as well as for point level detection a broad range of measuring principles is available. Endress+Hauser supports you from planning through commissioning and also maintenance of your measuring point.

When radar or guided microwave transmitters unexpectedly jump up the scale it can be due to a number of reasons;
Increased noise at the antenna due to build-up or condensation
Reduction in target echo strength due to foam formation or turbulence
Incorrect parameter setting or lack of mapping to the empty vessel during commissioning
The Micropilot free-space radar and Levelflex guided microwave transmitters from Endress+Hauser feature Multi-Echo tracking to help ensure reliable operation.

When dealing with foaming media the general principle is the lower the transmission frequency of the microwave device, the better the penetration of foam.
The Levelflex guided microwave transmitter from Endress+Hauser operates at 1GHz and is capable of reliably following liquid level below foam, but it is not well suited to vessels with agitation.
The Micropilot free-space radar transmitter from Endress+Hauser is available in three different frequencies.

It is possible to measure the interface between two liquid media if there is a big enough difference in density (with a float displacer), conductivity (with a capacitance probe) or dielectric (with a guided microwave transmitter).
The Endress+Hauser Levelflex FMP55 combines guided microwave and capacitance technologies to improve detection of the interface layer even with an emulsion present.
