Automation Direct have announced the EchoPod® and EchoSonic® II ultrasonic liquid level sensors which can be used to provide input data for control systems such as PLCs. Several models can also be configured for local level control using their 4 relay contacts to switch local valves and/or pumps.
The EchoPod DX10 / DL10 series ultrasonic liquid level transmitters provide continuous non-contact liquid level measurement output up to 1.25m. With the free WebCal software, .users can select the voltage or current output for interface with analogue inputs on control systems or select the frequency output for interfacing with frequency-capable or counter input discrete input cards. These non-contact liquid level sensors are ideally suited for corrosive, sticky or dirty liquids, and are broadly selected for small tanks. They use an optimised narrow 2″ beam optimised for small tanks.
The EchoPod DL series multi-function ultrasonic liquid level sensors offer a 4-20mA signal output and 4 programmable relays for level switch or level control functions. With these the WebCal software can also be used to configure the operation of the relays allowing them to be used as embedded level controllers. These non-contact liquid level sensors are, again, ideally suited for corrosive, sticky or dirty liquids. Analogue output models in ranges up to 1.25m, 3m or 5.5m.
The EchoSonic II LU series ultrasonic liquid level transmitters offer a 4-20mA signal output and are also configured via the free WebCal software. These non-contact liquid level sensors are ideally suited for corrosive, ultrapure, sticky or dirty liquids, and are broadly selected for bulk storage, dry tank, lift station and process tank level sensor applications. Ranges up to 3m, 5.5m, 8m and 10m are available. These units also include auto adaptive filters optimising signal output filtering and identifying obstacles.
