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.

 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

 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
