- Production:
- ASA (Italy)
Rotameters of model L ... 47_50 are made of stainless steel inox, certified by ATEX Ex ia IIC T4, T6 ... zone 0 and zone 1 (on request). Designed for use in potentially explosive environments due to its explosion-proof design. These instruments can satisfy requests for use in special conditions: dangerous areas, high temperatures, high pressures and low flow rates.
The L ... 47_50 rotameters are ideal for flow measurement where the safety and reliability of the instrument are required and the power supply of the device is absent (the standard model is equipped only with a flow indicator). The device allows to measure the flow in dangerous areas.
