Tokyo Keiso MASSMAX 7400R Series Coriolis Mass Flowmeter
Made in Japan
Manufacturer: Tokyo Keiso
Model: MASSMAX 7400R
The MASSMAX 7400R Coriolis mass flowmeter series consists of a popular single straight tube with low pressure loss and self-cleaning property, and the newly developed high-performance MMC400R converter. Innovative sensing technologies have eliminated restrictions on installation, achieving accurate flow measurement with simple mounting. Titanium is used for the measuring tube (wetted parts) as standard. Hastelloy®C22, Stainless Steel, and Tantalum are available on request. With 7 connection sizes from 6 mm to 80 mm, the MASSMAX 7400R covers various applications from small flow to large flow.
Features
- Completely straight single measuring tube. Excellent self-cleaning property and low pressure loss
- Simple installation eliminates the restrictions of on-site measures such as piping support and vibration shock reduction, saving space and cost
- High accuracy: ±0.1% of reading (+zero stability)
- Excellent zero stability and high vibration resistance
- Duplicated protection with outer cylinder made of Stainless Steel
- Simultaneous measurement of mass flow rate (instantaneous and totalized), density, and temperature with one instrument
- Compact type and remote type available
- Compliant with Japanese standard explosionproof
- Titanium is used for wetted parts as standard. Hastelloy®C22, Stainless Steel, and Tantalum are also available, covering a wide variety of applications
