Tokyo Keiso O7000 ORIFLOMETER
Made in Japan
Manufacturer: Tokyo Keiso
Model: O7000
The O7000 flow meter consists of an orifice plate and a metal tube variable area flow meter (AM7000).
By measuring a bypass flow of the” large sized” pipes with a” small sized” flow meter, the flow rate in the large pipes can be measured at low cost.
The robust and reliable local indicator can be equipped with the electric output, local flow integration with pulse output, alarm output and communication function to meet various applications.
Features
- High cost performance
A large flow through an orifice in the medium to large main pipe can be measured by measuring its small bypass flow at low cost. - Any flow direction
Bottom to top, top to bottom, left to right, right to left are acceptable. - Multi functions for various applications
Local indication, electric transmitter, local flow integration, pulse output of integrated flow, alarm output and communications are available. - HART® communications
- Explosionproof
Certified by TIIS, KOSHA, NEPSI, ATEX and IECEx - Protection class of indicator IP67
