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 waster water applications.

The USI Flow is optimised 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 touch screen 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.

USI FLOW, LEVEL AND WATER QUALITY FEATURES.

Windows Based Programming

Beautifully Simple – Windows CE is now recognized as a reliable and easy to use operating system. We are all familiar with its use in everyday life from computers to ATM machines. Smart Storm are proud to be the first company in this field to take the step forward to integrate Windows based programming into an industrial process and control instrument.

User friendly drop down menus, pop-up keypads, clear intuitive programming, pictorial graphics, visual representation of tanks, fast pick and selection of parameters, measurement simulation, both graphical and text displays, full colour background all combine to make the USI a truly user friendly experience.

Intuitive Programming

sampler-3-300x206

Smart Storm recognises that most industrial control products are a nightmare to programme and often come with a 200 page or more manual. Confusion and uncertainty often reigns when programming such instruments and small multi-line displays give little feedback to the user.

Hence, the USI offers a new dimension in intuitive programming. The software is wholly consumer orientated and intentionally designed to give the user a positive programming experience, without confusion and without uncertainty.

Programming options are instantly available through tab menus and give clear and precise options. Graphics are used to give clear choices when appropriate and parameter selection is simplicity itself. Programming pages are separated on the graphics display and once programmed the user can simply and easily review his programme choices on a single display screen. Just like a Smart phone the USI is quick and simple to navigate through!

 

Stunning Display

The USI uses a 7” TFT full colour 840×480 display to give sharp images and clear programming screens. In level applications tank shapes are selected from a pictorial map which does away with complicated programme selection as used by other manufacturers. Relays can be chosen from drop down menus and a graphical simulator is available to enable the user to simulate filling and emptying a tank in order to check his process control choice.

All information is clearly displayed thus avoiding confusion and uncertainty often found when programming other less advanced products.                                                                      The user even has the option to change background, text and shape colours to compensate for different ambient light conditions.

Data Report

The USI is unique in that the user can display data reports and time elapsed graphs of all measured data directly on its own graphics display without the need to download to a PC or laptop. No other instrument offers this versatility and by simply inserting the date fields required, data is instantly displayed and can be analysed in situ without the need to reload back at the office.

Of course if the user wishes the data can be downloaded onto a USB stick in seconds and reloaded onto a separate PC with data displayed through our freely available Windows package “Inquisitor”.

Multiple Communications

usi-10-300x200

The USI has it all – Ethernet connectivity for fast communications, 3×4-20mA inputs and 2×4-20mA outputs, a configurable UART for RS422 or Modbus connection and two USB ports for fast downloading of data.

Optionally, the user can have Profibus or GPRS for internet or mobile data connectivity.

 

High Performance as Standard

Incorporating the latest ARM and FPGA processors, full colour 7” graphics display, resistive touchscreen and 512Mbytes of storage the USI is faster and more fluid than any other product available.

Moving seamlessly across screens, with up to 20 years of data storage and on screen viewing of stored data both in tabular and graphical form, the USI takes measurement technology to a new level.

Vast Storage

sampler-8-300x200

The USI has up to 20 years of storage capacity for environmental measurement data.

Data can either be viewed on the USI itself or downloaded onto a USB stick or sent by Ethernet/GPRS to view on the windows based reporting software “Inquisitor” which is included with the product.

 

Remote Monitoring

The USI display screen can be viewed on a remote computer or through a GPRS modem. So at all times you can view the status of the USI without having to leave the office.

Great when sites are remote from your base or in numerous locations throughout the country and on rainy days it saves having to get the umbrella out.

1. Remote meters: Remote meters with 4-20mA outputs can be directly to the USI and scaled appropriately through the interactive menu.

2. Intelligent Modbus sensors are available from Smart Storm for environmental monitoring and up to 8 sensors can be daisy chained into the USI. This means there is no need for an independent second meter which provides vast cost savings, is more efficient and requires less space and cabling.

All information related to sensors can be found on the environmental sensors page.
