The F O Turbo-Lux 2 orifice plate flowmeter is used to measure the volume of water in closed pipelines. Any mounting position and flow direction are possible.
The main application is in stationary sprinkler systems. The flowmeter complies with the requirements of the Verband der Schadenversicherer e.V. (VdS) (association of damage insurers).
The F O Turbo-Lux 2 orifice plate flowmeter consists of a differential pressure sensor for stationary installation, and a portable bypass meter.
The differential pressure sensor largely corresponds to DIN EN ISO 5176 and the VDI guidelines 2040.
The bypass meter contains a conical glass tube with float . The water flows vertically upwards through the glass tube. A bypass orifice is located at the top of the tube. A filter at the inlet largely prevents the penetration of foreign matter.
The inlet and outlet for the flow measured in the bypass are arranged concentrically so that it is easy to combine with the stationary differential pressure sensor. |
