Thermal Mass Flow Meter

Insertion Flow Sensor for Compressed Air and Gases
The EE776 employs the thermal mass flow measurement principle and is suitable for pipe diameter DN50 (2") to DN700 (28"). It is ideal for monitoring and metering compressed air, nitrogen, CO2 and other non-corrosive and nonflammable gases with a pressure up to 16 bar (232 PSI). 

Versatility
The EE776 is available for two measuring ranges 0.2...100 m/s (40...19685 SFPM) and 0.2...200 m/s (40...39370 SFPM) and features various probes for maximum immersion depth 165 mm (6.5"), 315 mm (12.4") and 465 mm (18.3").

Wide choice of outputs
The measured data is available on two outputs, which can be configured as analogue current or voltage, switch or pulse signal for consumption metering. Optionally, the EE776 features also Modbus RTU or M-Bus (Meter-Bus) interface.

Easy and safe mounting
The patented non-return protection combines three functions:
▪ Non-return protection
The sensing probe can only slide in one direction during installation. It cannot return (blow out), even if released.
▪ Sealing An encapsulated O-ring avoids leakage when mounting the device under pressure.
▪ Precise positioning
The design facilitates the precise positioning of the sensing probe (immersion depth and orientation), which is paramount for high accuracy measurement.

User configurable and adjustable
The USB interface and the free software facilitate the EE776 configuration which includes selecting the measurands and the output signals, uploading the working pressure and the pipe diameter and adjusting the device.
