Battery Powered Electromagnetic
Volume Totalizing Meter

ETM3070 Series
OUTLINEThe ETM3070 Series is an eco-friendly electromagnetic volume
totalizing meter with high level performance and reliability. It has abuilt-in battery that ensures up to 10 years of continuous measuringperformance.
The measuring tube is lined with Rilsan® that is used to coat thesides of water supply pipes. The tube, configured in a concentricreducing design, has increased the accuracy in the domain of low
flow rate measuring.
The product can be used in a wide range of applications that utilize
water resources.

FEATURES❑ ‌It has a built-in lithium battery that ensures up to 10 years ofcontinuous measuring performance.
❑ ‌The die-cast aluminum measuring tube with a Rilsan®-coatedlining has excellent creep resistance against deformation caused
by vacuum pressure.
❑ Concentric‌
reducers used inside the measuring tube achieve highaccuracy in the domain of low flow rate measuring and required
lengths of upstream straight run: 3D (D: pipe diameter).
❑ Equipped‌with a grounding electrode, which eliminates the needfor grounding rings.
❑ Having‌the setting function of an infrared touch sensor allows
the user to switch the indication or set parameters from outside
without removing the cover.
❑ High‌accuracy - ±0.5% of reading❑ Empty‌
pipe detection feature

Note: Lower‌ambient temperatures will reduce the battery
performance.

Accuracy(*3)● Display

When flow velocity inside pipe is above 0.5 m/s: ±0.5% of reading
When flow velocity inside pipe is less than 0.5 m/s: ±0.2% of readingplus velocity error of ±0.0015 m/s

Accuracy (within ±xx% of reading):	Displays both the 8-digitvalue andthe remaining battery level
Values displayed:	Totalized volumes in m3 or
instantaneous flow rates in (m3/h)
are continuously displayed.		These values can be manuallychanged by a touch sensor.		Totalized forward-direction volume,totalized reverse-direction volume
or totalized differential volume canbe selected and displayed.
● Measurement sampling cycle
Setup value:	Selectable from 5, 10, 15 (standardsetting), and 20 s
* Depending‌on the sampling cycle, themaximum possible measuring time will
be limited by the battery. *For details,
refer to "Life of battery".
● Flow Low Cutoff
Setup value:	Selectable from 0, 5, and 10 mm/s
(standard setting) The standard settingof 10 mm/s prevents counting oftotalized volumes when the zero point
is unstable due to subtle movementsof the fluid during flow stoppages.
● ‌Pulse outputs
Open collector outputs (2 outputs)
Load rating: 2.7 to 24 VDC, 10 mA or less		 (Power consumption: Max. 100 mW)
Pulse rate
: 0.001 to 10 m3/pulse		
Max. output frequency: 500 Hz or lower
Pulse width:	Selectable from 5, 10, 20, 50, 100,and 200 ms● ‌Status output
Open collector outputs (2 outputs)
Load rating: 2.7 to 24 VDC, 10 mA or less		 (Power consumption: Max. 100 mW)		Used to detect instrument
malfunctions or for low battery level
