A very common output signal for sensors of all kinds, 4-20mA has a few very good reasons why it has been so popular for so long:
Long Cable Runs
The 4-20mA output allows for cable runs over 1000 ft. with almost no signal degradation and without regard to any voltage drops in the wire.
Remote networks are very useful in monitoring remote tanks. These can be monitored on a nearby local network or over the Internet from virtually any location. How, then, can you get a network or Internet connection to a remote location?
As sensor design engineers and manufacturers, liquid level sensors and pressure transducers can be broken down into two types: purpose built and field configurable.
A unique water distribution outfit in New England let’s customers fill their own bottles from a network of filling kiosks. The challenge? Keeping the kiosks stocked.
An abrupt change in a remote tank often spells disaster. These can be due to thefts and leaks or unusual usage patterns resulting in an overflow or a shortage. Even when the change is routine, a notification to verify data is always helpful.
Many of our customers are managing remote inventories of valuable commodities. There are a number of challenges keeping inventory managers in the dark about what’s really happening to their remote tanks. One of them is abrupt changes that are either unauthorized or unexpected.

Distributors and waste collectors of bulk liquids rely heavily on their trucks and remote tanks to transport and store product. This operation is quite expensive.
