Tokyo Keiso O3000 ORIFLOMETER
Made in Japan
Manufacturer: Tokyo Keiso
Model: O3000
The O3000 flowmeter consists of an orifice plate and a metal tube variable area flowmeter (AM3000).
It is designed to measure bypass flow by using a small flowmeter attached to the branch pipe, and thus to enable the measurement of flow rates in large pipes at low cost.
The indicators are selectable from the local indication type, electric transmitter type, and electric transmitter type with HART® communication.
Features
- Cost effective
The measuring method using an orifice plate enables the measurement of flow rates in medium- to large-size main pipes at low cost. - Omni-direction support (except O3□□□- AP)
Supports all directions from bottom to top, top to bottom, left to right, and right to left. - HART® communication
- Explosion-proof
Certified by TIIS, KOSHA, NEPSI, ATEX and IECEx. - Indicator protection category: IP67
