| LPG Dispenser Standard duty-Single CZ-LFM50 flowmeter | 4 | 40 | 2 |
Each CZL-******* dispenser consists at least of:
One measurement transducer (piston meter (CZ-LFM50)) with magnetic encoder (pulser (CZ-MGE-XX));
One electronic calculating/indicating device (CZ series calculator).
Optionally, a printer may be connected to the dispenser as follows:
Printer mounted on the dispenser door, powered and communication through the dispenser;
Printer mounted on the side of the dispenser, powered and communication through the dispenser;
Remote printer connected via the POS communication cable.
Optionally, an electro-magnetic totaliser (maximum volume indication 9999999 L) is also present on the dispenser.
The same housing of the dispenser can comprise of one or more measuring systems. When more than one measuring systems are in one housing, one calculating/indicating device may be a common part of the measuring systems.
The calculating/indicating device can have a maximum of 4 main displays, allowing it to configure and control 4 nozzles (meters), out of which 4 nozzles (meters) can be simultaneously operated.
A maximum of one nozzle (meter) can be connected to each calculating/indicating device's main display.
Approved input-Pulser communication cable via RS-485
Approved output - POS communication cable via RS-485
All communication cables (POS and Pulser) should be shielded cables.
A submerged pump is used for LPG dispensers. The LPG dispenser consist of a differential pressure valve DP050 which only allows the delivery to go ahead if the line pressure is greater than the vapour pressure. The differential pressure valve DP015 is a mandatory component.
