Piusi K33 & K44 Mechanical Flow Meters

Piusi K33 & K44 Flow Meters Product Summary

The Piusi K33 and K44 Flow Meters are designed to measure the quantity of dispensed diesel, biodiesel or light lubricant oil. The PIUSI K33 and K44 are mechanical flow meters suitable for the monitoring of diesel. PIUSI K33 as a mechanical flow meter has a partial indicator with 3 digits (max. 999 litres), total of 6 digits, while PIUSI K44 has a partial indicator with 4 digits (max. 9999 litres), with a total of 7 digits.

Ideal for use within commercial, industrial and agricultural installations, these flow meters are reliable, easy to install, simple to calibrate and are competitively priced. Thanks to reduced flow resistance the Piusi K33 and K44 Flow Meters can be used on gravity feed installations as well as pumped diesel and oil applications.

There is a pulsar model available that is fitted with a pulse emitter for connection to a fuel management system.

PLEASE NOTE: THESE FLOW METERS ARE NOT SUITABLE FOR RETAIL USE OR THE RE-SALE OF DIESEL, BIODIESEL OR OILS.

Precision & Quality

The K33 and K44 mechanical diesel flow meters have been designed for precise measurement of the quantity of fuels dispensed for non-commercial use. Easy to calibrate and install, the K33 and K44 flow meters can monitor the quantity dispensed for a maximum flow rate of 20-120 l/min and with a maximum working pressure of the pump of 10 bar. In addition, they can guarantee a burst pressure of 30 bar with a metering accuracy of +/- 1%.

Technical Features

• Aluminium metering chamber with Polybutylene nutating disk
• 1” F BSP Inlet and outlet ports
• The top can be rotated to give four different flow configurations
• Mechanical readout device with rotating wheels
• Subtotals can be set to zero, total readouts cannot. Available with litre units or gallon units
• The K44/P model is equipped with a pulse card, “open collector” type, externally powered by the receiver. Flanged coupling from both sides

Reliability

The K33 and K44 mechanical flow meter for diesel is easy to calibrate at the place of installation and is suitable for installation on pumps or service stations for diesel, for those who want to keep the amount of dispensed fluid monitored without special needs for storage.

K33 and K44 are reliable and economic mechanical flow meters that can also be used by gravity, thanks to the low resistance to flow. It is also available a pulser version of the meter which includes:

• Mod. Pulser: card type “Open collector”,
• frequency 10 pulses/litre,
• 6-24 V DC power supply, max. 10 mA.
