Piusi OCIO

• Automatic Tank Gauge, operates as a tank contents indicator
• Dimensions - 165mm L x 60mm W x 180mm H
• Accuracy +/-5-7%
• Probe Tubing is 10m L x 4mm ID 
• Material of the Probe Tubing is Rilsan
• Material of the Probe Weight is Brass
• Suitable for use with free venting, atmospheric tanks only, NOT suitable for use with any tank that is pressurised
• NOT suitable for use with Flammable Liquids
• %, litre and mm readings
• The maximum distance that the Piusi OCIO can be installed from a tank is 50m
• DN15 (½”) M BSP balance chamber fitting
• For tanks between 600-4000mm in diameter or height
• High / low level statuses can be set up
• two relays for connection to other equipment
• Suitable for Diesel
• IP54 Rated
• Reading Type: 0-100% / mm / inches / litres / gallons
• Capillary Type - 6 x 4 Rilsan PA12
• Brass Balance Chamber Weight
• Balance Chamber Fitting: 1/2" M BSP
• Max Working Temperature: -20ºc / +50ºc
• Suitable for Diesel, water, windscreen and lubricants if the additional oil kit is purchased
• The supplied probe is suitable for fluids having a viscosity lower than 30 Cst. (diesel oil, water, etc).  If Piusi OCIO is to be used with fluids having a viscosity between 30 and 2000 Cst, it is necessary to purchase the “Oil” type probe kit which is not supplied with with the Piusi OCIO.

How Piusi OCIO Works

• Piusi OCIO works on the principle of differential pressure
• A fluid contained in a tank applies a pressure at the bottom of the tank,
• The pressure at the bottom of the tank is determined by the level and density of liquid stored ( L )
• Piusi OCIO measures the pressure applied by the fluid through a probe which is held at the bottom of the tank by a weight.
• Given the value of the Density ( D ) of the fluid stored in the tank, Piusi OCIO will automatically calculate the surface level of the liquid within the tank and show it on the display.
• The Density ( D ) of any fluid can be easily entered in the instrument by calibrating the Piusi OCIO.
• A microchip placed on the electronic circuit board automatically activates a small electric compressor located inside the console as is necessary
• The compressed air, and a specially designed control valve maintains the required air supply within the probe
• The microchip also controls an integrated heater that prevents the temperature inside the housing to fall below a pre-determined value, in order to allow accurate readings and avoid the forming of condensate on the circuitry.

Piusi OCIO Alarms

• The Piusi OCIO includes two alarms which can be used for
  • activating remote devices (such as audible or visual alarms)
  • for stopping any pumps that may be connected to the tank.
• For each of the two alarms, both the normally open contact and the normally closed contact are available.
• i.e.: No. 3 connectors are available for both alarms.
• The alarms can be set only after configuring a tank.
• The alarms can be set independently from one another; this means that you can have:
  • two alarms of different kinds (one H-level alarm and one L-level alarm)
  • two alarms of the same kind (two H-level alarms or two L-level alarms).
