Heat meter calculator QALCOMET HEAT 1 PEQMH1V01

Configuration of calculator is possible via optical (or Wire) interface and in conjunction with the
programme SKS3knfg.exe
Parameterization (programming) procedure
Measurement schemes and energy calculation algorithms should be checked according to
individual heat meter data (see Paragraph 13), and other configuration parameters are entered:
- check measurement circuits (U0, U1, U2, U3, A1, A2, A3, A4) separately for the 1-st and
2-nd heating system according to Table 1
- check parameter registration algorithms for the 1-st and 2-nd heating system (see
Paragraph 4)
- check energy measurement units (MWh, Gcal, GJ)
- check pressure values used to calculate energy and fluid mass values individually for the
1-st and 2-nd heating system
Note: If pressure value is set to 0, energy and fluid mass consumed in that heating system
will be calculated using practically measured pressure values
- set (pre-program)

5 temperature value, if temperature sensor T5 is not used (only for A1
measurement scheme)
- flow, temperature and pressure measurement channels are activated (only for channels
that are used for measurement and connected to appropriate sensors). If energy calculation
algorithm “3 – winter / summer” is used, 4
-th flow sensor is disabled.
- select flow measurement display units (m
3
or t) (mass units
–
only for measurement
schemes from Table 1, where appropriate temperature sensors are used),
Individual parameters of flow, temperature and pressure sensors for each measurement channel
should be verified and pre-set:
- check flow sensor output pulse values for each measurement channel
- check maximum and minimum flow rate for each measurement channel
- pre-set designated minimum and maximum flow values, used for energy calculation when
measured flow rate exceeds allowed measurement limit
s (only when “2 – special” energy
calculation algorithm is used)
- check pulse input type:
“1” –
without cable detachment control
“2” –
with cable detachment control
–
sensor operation error is generated, when cable is
disconnected for more than 2 seconds
- minimum allowed pulse period (ms), used for pulse input noise filter (it is necessary to
define time interval from first received pulse, when additional received pulses will be
ignored). Selected time interval should be shorter than designated pulse period at
maximum allowed pulse frequency
Note: If value is set to 0, noise filter is turned off
- check temperature sensor type (e.g. Pt500,Pt1000) for each active measurement channel
- check normalized temperature difference for each pair of temperature sensors (

1-

2 and

3-

4). It should be not less than 2
o
C
- pre-set designated temperature difference value (

1-

2 or

3-

4), that will be used for
energy calculation when “2” – „special“ energy calculation algorithm is applied, and
temperature difference is under programmed minimum allowed value
- select normalized current limits for provided pressure sensors (0-5 mA, 0-20 mA or
4-20 mA)
- set pressure values for provided pressure sensors that correspond to upper designated
current limit.
Setting and verifying other parameters:
- set customer ID number
