The wall mounted Locator 3 comes complete with a 4-20mA output, RS232 and 3 programmable relays. The USM level works with the Digison range of ultrasonic sensors.
The USM is a powerful level monitor and controller ideal for cost-effective solutions. Using a smart ultrasonic sensor, the USM will measure up to 20m in liquids and 10m in solids. With all standard tank shapes available in the look-up menu and non-standard tanks programmable through a multipoint input table the USM will meet all your level and volume measurement requirements.
Simple pump control is available through the programmable relays and with a 4-20 mA output and an RS485 (Modbus) output the USM can readily communicate with other instruments.
Ultrasonic level monitoring often suffers from erroneous results due to false echoes from artifacts inside tanks and silos. The USM echo profile map can be accessed through a pc connected to the RS485 interface and false echoes simply removed from the profile allowing accurate and reliable level and volume measurement.
