- Level and Pump control
- Open Channel Flow
- Water quality measurement -pH, Redox, Dissolved Oxygen, Conductivity, Turbidity, Temperature
In common with all Smart Storm products the USM has been designed with the user in mind. Its four-button keypad allows fast and simple programming. The intuitive menus guide the user through clearly worded choice fields and help the user to navigate to a successfully programmed unit in a matter of minutes.
Water and Wastewater Specialists
Built on its research and advanced capability Smart Storm has always been at the forefront of innovative products for the water and wastewater industries and has won prestigious UK and European awards for its innovative technology.
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 nonstandard 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 4-20mA output and a RS485 (Modbus) output the USM can readily communicate with other instruments.
Ultrasonic level monitoring often suffers from erroneous results due to false echoes from artefacts 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.
- Ultrasonic Sensor for primary devices
- Non-standard look up table
- All standard Flumes and weirs
- Area Velocity Sensor for partially filled and surcharge pipes and open channels
The USM coupled with either a Digison ultrasonic airborne sensor for flumes and weirs or a Digison area velocity sensor for open channels, irrigation channels or pipes, offers a low-cost option for water and wastewater flow measurement.
All ISO type flumes and weirs are preprogramed into the USM for primary structures and for non-standard devices a 21-point look-up table is programmable. A Manning formula for numerous pre-programmed channel shapes and pipes allows simple set-up for area-velocity measurement.
Water Quality Measurement
- Dissolved Oxygen
As standard, the USM will measure one of a number of ISE (Ion Selective Electrodes), a Modbus Electrode, or a combination of the two so the user can measure two parameters at the same time. With a 3″ vibrant LCD graphics display and a 4-button interface, programming is extremely simple and user-friendly in both metric and imperial units. The USM pH Meter comes complete with a 20-year internet data logger, a 4-20mA output, a RS485 Modbus communications port and 3 fully programmable relays.
Sensor can be either free mounted in tanks or channels or inserted into pipes using Smart Storms bespoke pipe brackets. Additional to the USM environmental USM is an optional data logger which will record in excess of 22 years of data. A windows based reporting software package allows the user to download data using a USB port and display and print graphs and detailed reports.
