FMR504A Insertion Electromagnetic Flowmeter
The FMR504A electromagnetic flowmeter is ideal for measuring flow velocity and flow rate in water pipelines- it eliminates the total cost, including the construction cost.
- Construction can be carried out without interrupting the water service by fitting a commercially available corporation stop with saddle.
- Space-saving can install it in a short time and can largely reduce a cost of construction.
- Available for large diameter piping.
- Desorption is easy and bring excellent maintainability.
- Compatible with commercially available cables.
- Can calibrate actual flow rate with a user-specified flow rate.

※ FMR504A insertion electromagnetic flowmeter is for the pipe of water supply system, cannot be used for the fluid with foreign matter, adhesive substance or corrosiveness such as river water, agricultural water and sewage.
※ In this series, there is a FMR504AW that has a preamplifier in the detector side and a FMR504AR that has a terminal box. FMR504AW can be wired with commercially available cables due to the built-in preamplifier, however, should be avoided to install in the vibrating pipe or the place where the flooding is possible. For such case FMR504AR （with terminal box） is recommended.
