FLOATS-NBR
NITRILE (NBR) & POLYPROPYLENE FLOATS
Floats Nitrile and Polypropylene

Because these floats are 'foamed' they can be cut, drilled or shaped and still float!

Manufactured from either Nitrile (NBR) or Polypropylene, the Specific Gravity can be controlled to such high accuracy that they are even used to detect the interface between oil & water.

PVL has the UK's largest range of level switches in nitrile, polypropylene and stainless steel, manufactured by one of the world's leading companies in level switch technologies, Riko of Japan. This outstanding range includes level switches for viscous fluids, even sludge, custom-made level switches in a wide range of alternative materials to suit your process environment, level switches for tanks 10 metres deep, explosion-proof level switches and high-temperature level switches for fluids up to 180ºC and several types of side-entry level switch.

The PVL team can help you decide which level switch you need and, if there isn't a standard switch that does exactly what is needed, how to specify a custom switch to do the business. You have only to ask.
