To get a profitable and efficient management of the energy requirements necessary for the cycles of heating/cooling or DHW of the autonomous systems, it is essential to prepare an instrumental set that allows the collection of the fundamental data for the accounting of the physical heat. This allows not only to verify the accuracy of what is invoiced by the supplier, but also to make evaluations on the partialisation of the loads of the different thermal zones that make up the building.

This functional scheme describes two Kerberos proposals for measuring calorie/refrigeration consumption: the first (connection type 1) using an ultrasonic clamp-on meter with wall mounting,

KET-CCO-100, which sends the measurement to the ModBUS, KET-CCC-100 calorie counter via the 4-20 mA analogue output. Together with the temperature probes, these devices form the KET-KCO-100 kit.

In the second (connection type 2), an ultrasonic clamp-on meter with direct fixing to the supply line, KET-CCO-310, is used, which, unlike the first case, transmits the pulses to the KET-CCC-100. Together with the temperature probes, these devices form the KET-KCO-310 kit.

The KET-CCC-100, via RS485, sends the data to the KET-GZE-220 gateway, present in the same electrical cabinet (Panel 1), for display on external platforms such as X-Platform Easy.

KET-GZE-220

It is a gateway with ethernet interface and radio module, with ModBUS Master function for up to 32 slave profiles and datalogger with data recording capacity for periods longer than 3 months.  

Kerberos offers as additional services the preconfiguration and insertion in a pre-wired electrical panel (Panel 1) of the devices for quick and easy installation, and the X-Platform Easy platform for data acquisition and visualization, configurable to your needs.

KET-MUM-100

Industrial type modem, it interfaces with the gateway via Ethernet port. Equipped with the main security certifications, guarantees the connection even in the absence of a local network, Kerberos provides, as an additional service, a SIM for data traffic with annual fee contract at very advantageous prices. It can be supplied pre-configured and inserted in the electrical panel (Panel 1).

KET-CCC-100

It is a ModBUS thermal energy meter in compliance with EN1434, equipped with analogical, digital, frequency and temperature probe (flow/return) inputs. It uses 6 ModBUS Slave profiles and therefore a maximum of 5 can be connected for each ModBUS Master. It can be supplied pre-configured and inserted in the electrical panel (Panel 1).

KET-CC0-100

It is an ultrasonic thermal energy meter, the measuring principle is based on the transit time with double DSP technology for greater accuracy. It sends the data to the KET-CCC-100 via a 4-20 mA output. It can be supplied pre-configured.

KET-CC0-310

It is an ultrasonic thermal energy meter with direct fixing on the flow pipe, the measuring principle is based on the transit time for the flow measurement. It sends the data to the KET-CCC-100 via pulses.

It can be supplied pre-configured.

KET-SPT

Kerberos has many types of temperature probes: PT100/500/1000, 2-wire or 4-wire, MID certified, different cable lengths, etc..
