Root Type Positive Displacement Flow Meter Model JA (Standard Type)
| Model | : | JA (Standard Type) |
| Manufacturer | : | NEW - FLOW |
| Origin | : | TAIWAN |
The Principle
The flow meter was designed a special two rotary of Roots for measuring the volume of liquid fluid when the fluid running into the meter pushes two Roots, The driving roots drive a magnet coupling with a direct gear. Then the magnet coupling transmit to the totalizing counts with a gear too. It comes to measure the amount of the fluid which pass to the meter.
