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.

Product Details-

• The EE741 in-line flow meter can be easily adapted for any measuring task. It is dedicated for accurate metering and monitoring of compressed air and technical gases in DN 15 to DN50 pipes.
• The thermal measuring principle and the well proven E+E hot film sensor element lead to best long-term stability and fast response time.
• Outstanding measuring accuracy, even in the lower measuring range, is achieved by an application-specific multi-point factory adjustment performed at 7 bar (102 psi). This allows reliable leak detection and corresponding energy savings. The construction of the EE741 flow meter is optimised for easy installation and maintenance.
• Modular design
• One and the same transmitter can be used for each of three pipe diameters:
• EE741: DN15 (1/2") / DN20 (3/4") / DN25 (1")
• EE741-N50: DN32 (1-1/4") / DN40 (1-1/2") / DN50 (2")
• The pipe diameter is easily set via the display menu or the EE-PCS product configuration software.
• Once the gauge mounting block is installed in the pipeline, the transmitter can be installed and removed without any pipework. As a result, the EE741 flow meter is also ideal for temporary measurement at several installed mounting blocks. The sealing plug included in the scope of supply enable the normal operation of the compressed air system when the transmitter is removed.
• Display (optional)
• The state-of-the-art LCD shows the current measured values and the overall consumption. The EE741 setup can be easily performed with the push buttons and intuitive menu guidance. The display can be rotated in 90° increments with a push button for convenient orientation in any mounting position of the flow meter.
