The main benefit of loop-powered meters is they can be powered directly from the 4-20 mA loop. So if you need a local tank side indicator for an existing 4-20 level transmitter, all you have to do is break the wires and install the indicator.
The main benefit of line-powered meters is they provide the 24 VDC to power the 4-20 mA level transmitter and can be equipped with optional relays for alarming and controlling applications. This makes them ideal for sump pump control applications; even in hazardous areas!
