By-pass level gauge and switch for oil industry, food industry and chemical industry. It can be mounted on the side of the tanks with two standard flanges. In the by-pass body, the floater following the liquid level changes moves the leafs. It can be operated without auxiliary power. The level gauge can be read from long distance. The sensors of OMUV 05 type instruments can also be built into this level gauge, thus the instrument can be used for level switching, exact level measurement with resolutions of 5-10-25 mm, and remote level indication. The gauge body made of stainless steel (no danger for glass breaking). Polypropylen body if needed for strong acids (HCl),
The level indicator works from -60° up to +180°C ambient temperature.
The sensors of OMUV 05 type instruments can also be built into this level gauge, thus the instrument can be used for level switching, exact level measurement with resolutions of 5-10-25 mm, and remote level indication (two-in-one solution).
Choosing the right sensors:
- level switch: its sensors are magnetic switches, reed relais. Operation: bistable reed switching on to rising level, monostable
- level transmitter: built from reed relais and resistors with 4..20 or resistance output signal
The floater of all OMUV 09 instruments can be adjusted to float at the boundary of the two media, on the phase boundary. Thus the instrument can be used for accurate (even with a 5-10-25 mm accuracy) remote indication and phase boundary measurement. The difference in the densities of the two media should be at least 300 kg/m3, and the density of the lower density medium should be at least 450 kg/m3.
For smaller tanks we recommend the OMUV 09-6 with 10mm leafs, for normal tanks recommended the 33mm - easy to read form far distances - version.
