Condensing Advanced Features and Compact Body

ryuki em series differential pressure flowmeter

An EM differential pressure type flow meter that condenses advanced features and abundant functions in a compact body. Since a metal diaphragm is used for the pressure-receiving a part, it has a structure that can withstand high line pressure.

A two-wire flow meter that can be wired from either the left or right side. In addition, it has a waterproof structure that can withstand temporary flooding and has excellent water resistance. It can be easily installed in the middle of wiring for on-site instructions and remote transmission. “It can also be used with the ODM-300 indicator unit.”

Features

  • Built-in semiconductor compound sensor and microcomputer, convert measured flow rate to DC 4-20mA signal.
  • Since a metal diaphragm is used for the pressure-receiving a part, it has a structure that can withstand high line pressure.
  • The transmitter has a compact body of approximately 3.5 kg and is small and lightweight.
  • It is a 2-wire flow meter that can be wired from either the left or right side.
  • Adopts a water-proof structure (JIS C0920) that can withstand temporary flooding and has excellent waterproof properties.
  • Easy installation in the middle of piping for on-site instructions and remote transmission.
