Compliance and Restrictions

  • This product has been certified by a third party to be compliant with the “Safe Drinking Water Act” requirements for low lead in potable (human consumption - drinking and cooking) and non-potable water applications (non-human consumption).


EchoSwitch® general-purpose sensor provides continuous noncontact level detection with 3 programmable relays for level switch or control functions and 4-20mA signal output. The sensor is programmed by an integrated push-button display module. Each relay can be configured on a single set point (high or low level alarm) or latched on 2 set points for automatic fill/empty in simplex (1 pump or valve), duplex (2 pumps), or triplex (3 pumps) level control modes with selectable time delay and fail-safe logic. Embedded level controller can reduce costs by replacing external control hardware. Noncontact sensor is excellent for corrosive, sticky, or dirty liquids, and is broadly selected for pump lift station, sump, and dry tank level applications.
