USI Flow, pH and Water Quality Meter

The USI Flow is an advanced data logger for monitoring flow and water quality. With the capability to monitor flow alongside water quality measurements, and an integrated input specifically for pH, the USI can replace a number of individual instruments or avoid having to build a custom PLC in a wide range of clean water and wastewater applications.

The USI Flow is optimized for use with Smart Storm non-contact Ultrasonic Sensors which are renowned for their high accuracy and durability in open channel flow measurement but can also be used with Magnetic Flowmeters (Magflow) for the monitoring of closed pipe flow. Smart Storm Water Quality Sensors can be connected directly to the USI Flow for the monitoring of up to four water quality parameters.

USI Flow sets itself apart from traditional instrumentation by using an intuitive touchscreen interface and displaying real-time data and graphs on its 7-inch high-resolution screen. This provides the user with unrivaled accessibility and clarity of information and allows field users to access information instantly. The USI software is as intuitive and simple to operate as a home computer, which makes both programming and operation simple and efficient for engineers and operators.

The USI Flow contains 4 Modbus inputs for the environmental sensors. 4 non-isolated 4-20 mA inputs and 2 isolated 4-20 mA outputs, Ethernet and RS422 or Modbus communications and 6 programmable relays.
