The OMNI-TUF-200LW is a low flow transducer assembly available for the OMNI-TUF-200M and OMNI-TUF-200F series ultrasonic flow meters.  This robust transducer is designed to measure flow rates from 1.7 liters per minute (57 oz) to 9 liters per minute (300 oz) at a low liquid pressure from 0 to 0.5Mpa.  The PFA construction allows this transducer to be used in applications where contamination is a concern and yet is able to withstand many corrosive mediums.  Since there are no moving parts, the flow is measured using the ultrasonic time of flight principle, allowing a 1% accuracy while not disturbing the flow.

Using the 200M or 200F flow meters, the OMNI-TUF-200LW can display its flow rate and total readings in real-time, output a 4-20mA, pulse, RS485 or MODBUS signal.  The build in data logger, or optional 2GB SD memory card option will allow you to install the meter in long term monitoring applications.

Both the standard TUF Series Wall Mount and DIN Rail mount have an internal memory capable of storing 500 lines of data.  Our new 2GB memory option allows you to increase the internal memory to store millions of readings, allowing a more detailed flow analysis to be captured.  The memory option features a SD removable memory card allowing easy data download without taking your laptop to the site.  All parameters can be stored on the card such as flow rates, volume, error messages and power down/up times.

The memory card option fits in the standard OMNI-TUF-200F ultrasonic flow meter case while the OMNI-TUF-200M has to be ordered with its optional enclosure to allow adequate protection for the memory card.

Our popular, low cost, wall mount ultrasonic flow meter is now available in its second revision.  Building on the performance of the previous model, the new version adds additional communication options, improved energy monitoring and a new, smaller, case with an easy to use front keypad which can be operated without opening the door.  As with the previous model, the keypad can be locked by setting your own PIN number and the display can be programmed to display various values such as flow rate, meter status, running time and net, positive and negative flow totals.

Our ultrasonic time of flight flow meter can easily be installed and used in a variety of applications which have a clean liquid flow.  Mediums such as water, oil and various chemical mixtures can be accurately measured.  Almost all types of pipe materials are supported including PVC, schedule 40, copper iron, stainless steel and many more.  Outputs include relay alarms, MODBUS, 4-20mA and pulse are standard, as well as two analogue inputs and RTD’s.  Thermal energy monitoring is included as standard allowing you to constantly monitor your plants efficiency.  A built in data logger allows for stand alone operation.

The news TMS3000 advanced airflow measurement sensor system from Schiltknecht is designed for ventilation and control in road tunnels.  The ventilation of road tunnels ensures that toxic gases (above all carbon monoxide) and dirt particles are removed from the tunnels.  The airflow measurement system features a robust, no moving parts, sensor design which offers near maintenance free operation.  The advanced field transmitter allows you to design an optimal fit for your tunnel geometry and is not effected by traffic unlike similar ultrasonic systems.

All the electronic components are located away from the high traffic driving area which allows easy servicing and continuous measurements even in extreme conditions such as fire, up to 1200°C!  By using differential pressure measurement this has many advantages including high accuracy and high resolution, <0.1 m/s, flow measurements.
