Metal tube Variable Area Flowmeters for small flow measureme

M-900 is a series of Metal Tube Variable Area Flowmeters designed for small flow.
M-900 covers high temperature and pressure applications which are not acceptable glass tube Purgemeter.
In addition to local flow rate indication by a scale and a pointer, alarm contact or electric analog output is available.
For low pressure gas, less than 0.29 MPa, a damper can be equipped with.
