MEMS technology provides super flow
sensitivity
A new supersensitive gas flow sensor based on proprietary MEMS technology is able to measure gas velocity and direction at extremely low flow rates.
A new supersensitive gas flow sensor from Omron, based on proprietary MEMS technology is able to measure gas velocity and direction at extremely low flow rates, and is ideal for looking at low pressure medical gases, boiler emissions and HVAC system airflow As a result of its sensitivity, the new Omron D6F sensor allows the precise monitoring of the presence and circulation of gases in the environment in a way which was previously often uneconomical

Distribution boxes simplify field connections
Multiport distribution boxes simplify the applied wiring of sensor actuators, enabling multiple connections in an area with just one connection going back to the controller.
Snap mounting eases sensor installation
The novel mounting system used with E3FZ sensors completely eliminates the need for nuts and screws.
It is suitable for measuring the amount of oxygen and nitrogen dioxide consumed from a respiratory apparatus in surgery.
It can also be used to monitor levels of carbon monoxide and nitrogen generated through incomplete combustion or the amount of flammable gas and air in order to achieve complete combustion for a hot water boiler.
A further application is monitoring air circulation in a building and thus improving the performance and efficiency of air conditioning and building comfort systems.
Capable of highly accurate measurements over a wider temperature range compared with conventional mass flow meters, the Omron D6F can detect gas flows of just 0.5cm/s or less to an accuracy of +/-3% of full scale.
It detects air, nitrogen, city gas and other non-corrosive gases.
The extreme sensitivity is achieved with a tiny heating element, associated with temperature sensors on both sides.
The deviation in temperature measured by the two sensors is used to calculate the gas flow and direction, generating a non-linear analogue output in the range 1 to 5V.
The exceptional performance of the D6F is achieved using the world's smallest, supersensitive flow sensor elements with an area of just 1.5mm2, achieving a size of just one-seventh that of other flow sensors in the same class.
The D6F is suitable for gas flows of up to 10m/s from any direction. Request a free brochure from Omron Electronics ...
