Installation

Battery Powered Electromagnetic Flow Meter Installation Requirement
In order to obtain a stable and accurate flow measurement, it is very important that the flow meter is installed correctly in the pipe system.
Do not install the meter near equipment that produces electrical interference such as electric motors, transformers, variable frequency, power cables etc.
Avoid locations with pipe vibrations for example pumps.
Do not install the meter close to pipeline valves, fittings or impediments which can cause flow disturbances.
Place the meter where there is enough access for installation and maintenance tasks.

lnstall at the lowest point and vertical upward direction Don't install at the highest point or vertical downward diection	When drop is more than 5m, install exhaust valve at the downstream
lnstall at the lowest point when used in open drain pipe	Need 10D of upstream and 5D of downstream
Dont' install it at the entrance of pump, install it at the exit of pump	lnstall at the rising direction
