GENERAL Application Honeywell EW10 Series multijet water meters are used for flow measurement of cold or warm water in potable water systems. They are available in sizes DN15 to DN0 and have an electronic counter with optical interface as well as M-Bus or RF output. EW100 water meters are suitable for cold water up to 0 C. EW101 water meters are suitable for warm water up to 90 C. Features Available with either M-Bus or RF Electronic sensor control for flow rate recording Lithium battery, lifetime 10 years Optical interface included as standard Adjustable reading date for billing Rotatable integrator Single-line 7-digit display for easy reading Design EW10 Series water meters consist of: Rotatable electronic counter with optical interface M-Bus or RF output Multijet mechanical flow measuring unit Housing with external threads according to ISO228 on inlet and outlet Materials Electronic counter housing and flow measuring unit made of plastic Housing of multijet flow sensor made of brass Approvals Table 1.

It is permanently fixed to the flow sensor but can be rotated for better readability The meter can be read from a single line seven-digit display with units and symbols. A push button provides control of various display loops. All failures and faults are recorded automatically and displayed on the LCD screen. For protection all relevant data is saved in a volatile memory. This memory saves measured values, device parameters and types of error at regular intervals Flow Sensor The multijet technology of the flow sensor combines high measuring accuracy with long term stability. The impeller is connected to the counter by inductive sensing. Power Supply Lithium battery.0v DC with 10 year nominal lifetime. Interfaces EW10 Series water meters are equipped with a ZVEI optical interface for communication and testing as standard. EW10xBF versions additionally have an 868MHz RF module on board as standard. EW10xBM versions additionally have an M-Bus interface on board as standard. For more details on interfaces see chapter Communication and Readout below. Honeywell All rights reserved EN0H-015GE25 R01
Installation Calming legs before or after EW10 Series multijet water meters are not required Sizes DN15 20 may be installed in any position Sizes DN25 0 may only be installed in horizontal position Avoid installation at highest point of system or system part as air may be trapped in meter It is recommended to place a ballvalve before and after the meter for easy replacement During measurement meter must be completely filled with water Communication and Readout Communication Options EW10 Series water meters have an optical interface on the front panel and either an RF or M-Bus interface. OS-Numbers starting with EW100BF and EW101BF have an RF interface EW100BM and EW101BM have an M-Bus interface Optical interface on front panel Included as standard in all EW10 Series water meters. ZVEI interface, M-Bus protocol, for readout and parametrisation. Required for access to meter: Bluetooth optohead (EWA001799) PC with HydroSet software RF interface Transmission interval 6 seconds, suitable for walk by and fixed RF networks. Open Metering Standard protocol, frequency 868MHz. M-Bus interface Configurable telegram, according to EN1757-, data reading and parametrisation via two wires with polarity reversal protection, auto baud detection (00 and 200 baud), 2 M-Bus connections with 2 primary adresses. Readout Options Manual readout by visiting meter and reading consumption values off display Optical: by visiting meter and reading consumption values out via optical interface RF: remote readout by attaching meter to a mobile or fixed RF network M-Bus: remote readout by attaching meter to an M-Bus network Setup Table. Readout options EW10 Series EW100BM, EW101BM Onboard RF RF transmission must be actived by pressing button on frontplate RF status can be checked by toggling through main loop of display. RF status is shown after display check: UHF OFF or UHF On, also see installation and setup instructions supplied with device Once RF is activated it can only be deactivated over the optical interface. See above Onboard M-Bus No field setup at meter required. Identification Meter Identification in the Field EW100BF, EW101BF Optical With BT optohead EWA001799, HydroSet software and suitable PC Pulse Not possible M-Bus Included as standard With M-Bus receiver EW55M011 RF With RF module EW9100AEZ001 Included as standard Electronic counter EW10xBM (M-Bus): white round rotatable counter housing permanently fixed to flow sensor housing EW10xBF (RF): white round rotatable counter housing with bulge above display for RF antenna.
