Page 6: Product Description
Product Description The EE741 flow sensor operates on the thermal mass flow measurement principle and is suitable for measuring the flow of compressed air and gases in pipelines. It can be used for measuring the consumption of compressed air, nitrogen, argon, oxygen, CO or other non-corrosive and non-flammable gases. -
Page 7: Modular Design
Modular Design One and the same sensing unit can be used for each of three pipe diameters: EE741: DN15 / DN20 / DN25 (1/2") (3/4") (1") EE741-N50: DN32 / DN40 / DN50 (1-1/4") (1-1/2") (2") The pipe diameter is easily changed via the display menu or the EE-PCS Product Configurator Software (available for free download at www.epluse.com/... -

Page 16: Digital Interface
Digital Interface 5.2.1 M-Bus (Meter Bus) The M-Bus (Meter Bus) is a field bus for recording consumption data. Transmission runs serially on a reverse polarity protected two-wire line. The EE741 flow sensor as M-Bus slave requires a separate supply voltage. There is no prescribed specific topology (line or star) for the wiring. Normal phone cable of type J-Y(St)Y Nx2x0.8 mm can be used. -
Page 17: Modbus Rtu
5.2.2 Modbus RTU EE741 flow sensor can be operated in a Modbus RTU network with max. 32 devices. Writing 0 into the corresponding register will reset the MIN/MAX values and the consumption meter. For Modbus protocol settings see Application Note Modbus AN0103 (www.epluse.com/EE741). Modbus Map: Register number Register address... - Page 18 The recommended baud rate for several devices in the Modbus RTU network is 9600. Device address, baud rate, parity and stop bits can be set via: 1. EE-PCS, Product Configuration Software and USB configuration interface (see chapter 5.3). The EE-PCS can be downloaded free of charge from www.epluse.com/configurator 2.
