Communication with meters CALMEX VKP calorimetric meter
is a calorimetric meter produced by the Sensus Metering Systems, a.s
company (formerly PREMEX-IN
, Invensys metering system
), Stará Turá, Slovakia.
For this communication in the PROMOTIC system can be used: PmMBus - Driver for communication with M-BUS protocol
For easy integration of this driver into the application it is handy to use:
The meter has only one message type. The data in this message are not in standard M-BUS form (do not have DIF/VIF
) therefore the data is obtained according to the meter documentation. It is not possible to use the PmCommData
object for this meter because the message does not contain any standard values.
Preset message types for PmCommMsg
- Reading of measured values
There are following variables on the Data-received page: Header of M-BUS message (only Addres and IdentNr) followed by: heat quantity (Q), heat performance (P), flow volume (V), flow rate (F), Forward temperature [°C] (T1), Return temperature [°C] (T2), etc. (all values contained in the message are received).
Because of the non-standard data the values are not counted automaticaly in standard units. The information about the measurement units are stored in additional data (e.g. K1Q, K1P, etc.). The received data is described in Note in automaticaly generated variables.
