EW105 Series Singlejet Pulse Out Water Meters DN15…20 FOR POTABLE WATER APPLICATIONS PRODUCT DATA Application Honeywell EW105 singlejet pulse out water meters are used for measurement of water consumption in residential applications. They are available in DN15…20 and have a mechanical roller counter attached to a singlejet flow sensor. They are fitted with a pulse out cable for remote readout applications. EW105 singlejet water meters have MID approval. Features Fully resistant to external magnetic fields Robust singlejet flow sensor Pulse output as standard Specifications Sizes DN15…20 Q3 2.5…4m³/h Medium Cold or warm potable water Temperature class (medium temperature) EW1050: T30, T50 (0.1…50°C) EW1051: T90 (0.1…90°C) Water pressure class MAP16 (max. 16bar) Design and Materials Pressure loss class ∆P63 (max. 63kPa @ Q3) EW105 water meters consist of: Environmental classes B / M1 / E1 Mechanical roller counter with 5 digits in metal housing Measuring process Mechanical dry dial counter with singlejet volume measurement Display Roller counter, 5-digit Display unit m³ Installation position H, V (horizontal, vertical) Interface Pulse out Installation Approval MID Calming legs before or after EW105 water meters are not required Function A distance of 5 x DN before and 3 x DN behind the meter is required from pumps, T-pieces or self acting valves Counter: the meter is equipped with a mechanical roller counter for volume metering of cold or warm potable water. It has a five digit display. Counter and flow sensor are secured by a permanently fixed and sealed clamp Non removable clamp between housing and flow sensor Singlejet flow sensor with magnetic clutch Brass flow sensor housing with external threads according to ISO228 on inlet and outlet All types may be installed in horizontal or vertical position, with counter facing upwards or sideways 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 Honeywell • All rights reserved Flow sensor: the singlejet technology of the flow sensor combines high measuring accuracy with long term stability and low starting volume Interfaces: EW105 water meters are equiped with a pulse out cable with a value of 10 litres / pulse EN0H-0453GE25 R0115 EW105 SERIES SINGLEJET PULSE OUT WATER METERS Dimensions and Ordering Information Fig. 1 Table 1.
