RAGL Rotameter Flow Meter
Brand: Yokogawa Electric CorporationThe RAGL Laboratory Rotameter is ideal for measuring low flows of liquids and gases, designed with a conical glass metering tube that has a free rotating float, which is mounted in a vertical pipeline with flow direction upwards.
In addition, its anti-static metering tubes allow for measurement of small quantities of gas, delivering high accuracy at low flow rates.
The flow is indicated by the top of the float and can be read from the standard scale on the metering tube or from a connected scale.
Meets High Safety Standards:
The RAGL’s tube is sealed with o-rings and additional tube gaskets, which are fixed with pressure flanges for high tightness, providing a higher level of safety.
Features- Needle valves direct assembled in the head of the inlet or the outlet
- Inductive ring sensors as limit switches available
- Inlet and outlet flow controller available
- Frame for panel mounting available
- Foot plate for table installation available
