[1] The $ Q_{\mathrm{min}} $ flowrate through each individual flow meters in the parallel configuration shall not be smaller than the $ Q_{\mathrm{min}} $ of the individual meter (2 L/min);
The $ Q_{\mathrm{m a x}} $ flowrate through each individual flow meters in the parallel configuration shall not be greater than the $ Q_{\mathrm{m a x}} $ of the individual meter (80 L/min).
Each CZF-******* dispenser consists at least of:
- One combined vane pump and gas eliminator device (CZ-VP080);
A gas separator is not essential if submersible pump is used, in this case measures should be taken on the supply tank to make sure that air or gas is not introduced in the system.
One measurement transducer (piston meter (CZ-FM120)) with magnetic encoder (pulser (CZ-MGE-XX)).
One electronic calculating/indicating device (CZ series calculator).
Optionally, a printer may be connected to the dispenser.
The Printer, if connected is a non-mandatory ancillary device and thus not subject to control. Each printout of transaction intended for the customer should bear the legend "Legally not relevant" on it.
The fuel dispenser has an option for vapour recovery.
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 8 nozzles (meters), out of which 4 nozzles (meters) can be simultaneously operated.
A maximum of four nozzles (meters) can be connected to each calculating/indicating device's main display, only one nozzle out of the four connected to a single display can be simultaneously operated.

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.
For standard and heavy-duty application, a single meter is used to deliver fuel through the hydraulic path for each nozzle.
For ultra-heavy-duty applications two meters are connected in parallel to deliver fuel through a single nozzle.
