  • Due to the two calibration curves the sensor can be used with highest precision in two different gases
  • Velocity, Flowrate, Consumption and Temperature are displayed
  • IP65 protection class offers a rugged protection in rough industrial environment
  • Isolated analog and pulse outputs or MODBUS/RTU interface
  • Thermal mass flow measurement, pressure and temperature independent
  • Very fast response time, high precision and wide measuring range

    The S 401 flow and consumption sensor covers a wide measuring range. With the high resolution and sampling rate a very fast and precise measurement is achieved. The sensors is able to save two calibration curves, due to this the sensor can be used in two different gases without any loss of accuracy. The optional color display is designed to show all measured values, at the same time it can be used to manage the sensor settings like pipe diameter, gas type or analog output scaling. The sensor offers two different signal output options. It can have a isolated analog and pulse output to read out the flow and the total consumption. Alternatively a MODBUS/RTU interface can be used to access all measured values via the digital interface.

    Various settings such as gas type, flow unit, reference standards, can be set ex factory, through our service kit or through the optional display. The service kit consists of a PC software and a interface box which connects the flow meter to the USB port of the PC.

The Nexuz flow sensor S 450 is based on the thermal mass flow principle. It measures volumetric standard flow over a wide measuring range. The result is pressure and temperature independent.

The S 450 is designed specifically for harsh environments. The enclosure with IP67 allows all-weather applications, all parts which come into contact with the measurement medium are made of stainless steel 316L. This allows applications in pharmaceutical and food industry, but also the measurement of corrosive and contaminated gas. Installations in explosive environment can be done through the optional ATEX approval. Various gases can be measured such as air, oxygen, argon, carbondioxyde, natural gas, hydrogen, methane, etc. Basically any gas mixture can be measured as long the mixing ratio and its components are known and constant.
