Danfoss SonoMeter40 Heat and Cooling Meter User Guide

Danfoss SonoMeter40 Heat and Cooling Meter

Purpose

Configuration software SonoMeter_40_UserConfig.exe is designed for SonoMeter 40 heat meters installation, maintenance and inspection/adjusting employees. Main functions:

• Reading meter configuration and performance of its maintenance;
• Modification of new meters before start of commissioning (when the meter is in Transport mode);
• Modification of meters after changing the operating conditions;
• Facilitation of meter verification;
• Meter modification during verification;
• Current data and archive data reading.

Main information

• The meter configuration can be read and modified at any time via optic interface or M-Bus/CL/Mini-Bus wired interfaces (if wired interface is supplied) regardless of the operating mode of the meter. The scope of modification configuration depends on the operating modes activated in the meter  (see, Table 5.1).

• When idle, the optic interface of the meter is inactive; in order to activate it (active time – 5 minutes), it is necessary to press the meter button. The meter will be automatically deactivated in 5 minutes after the last hit of a button or the end of the last communication via the optic interface.

• The wired interfaces are always active (unless their operating credit limit has been reached). Communication speed of optical interface – 2400bps, parity – Even. Communication speed of wired interface may be adjusted according to the client’s needs, which is displayed in the meter’s LCD menu. In case of standard reading: 2400 bps, parity – Even.

• The operating mode of the meter may be changed by ADJ and SERVICE contacts, which are concealed and can be reached by breaking open the plates provided on the back of the box marked as ADJ and SERVICE. The respective mode can be activated by using any metal tool to short the contacts; the mode can be deactivated by shorting the contacts again. Following configuration,
  the access must be blocked by special seal stickers, which shall be waterproof and/or resistant to temperature fluctuations: The ADJ window shall be closed with a metrology seal, the SERVICE window – with a supplier’s seal.
  Important: Prior to modification of the meter’s configuration, the existing meter configuration must always be read first.

• The available meter operating modes, their purpose and activation method are provided in Table 2.1.

Modification of configuration

1. The configuration scope allowed to be modified depends on the operating mode of the activated meter (see, Table 5.1).
2. The new parameter values required for modification of configuration must be entered in the windows (or selected from the list, or checked), then Write configuration must be pressed.
3. The meter configuration can be saved in a file (by pressing Store configuration) or restored from the saved file (by pressing Restore configuration and Write configuration).

Rates configuration features (see the configuration window Device configuration).

  *  **Tariff 1 (2) Counter –** selection of the tariff counter type: E – heating energy counter, E* – cooling energy counter.
  *  **Tariff 1 (2) Trigger –** the parameter, the value of which controls the tariff switch: P – thermal input; Q – debit; T1 (T2) –
  *  **temperature; dT –** temperature difference; time – time interval per day; Input 1 (2) – pulse input level (shorted or open).
  *  **Tariff 1 (2) Threshold –** the parameter threshold value, which triggers tariff activation (parameter units are indicated in the Trigger window).
  *  **Tariff 1 (2) condition –** tariff activation condition:
  * If MIN applies, the tariff will be activated when the measured parameter value is higher than Tariff 1 (2) Threshold value (in relation to time – if the current time is within the Tariff 1 (2) Threshold time interval limit;  

In case of Input 1 (2) – if there is a low voltage level in the respective pulse input or it is shored)

  * If MAX applies, the tariff will be activated when the measured parameter value is lower than Tariff 1 (2) Threshold value (in relation to time – if the current time is outside Tariff 1 (2) Threshold time interval limit;  

In case of Input 1 (2) – if there is a high voltage level in the respective pulse input or it is open)

  * If MIN-MAX applies – the tariff will be activated when the measured parameter value is within the Threshold value interval. In this case, Tariff 1 and Tariff 2 are interdependent. MIN-MAX condition does not apply where the time or Input 1 (2) parameters are selected.
  * If MIN-MAX condition is selected for the Tariff 1, then Max threshold corresponds to Tariff 2 Threshold window, while Min threshold corresponds to Tariff 1 Threshold window. The Counter and Trigger parameters of Tariff 1 are automatically compared to Tariff 1 parameters, with MIN condition selected automatically. Tariff 2 will become active where the measured parameter value is higher than Tariff 2 Threshold value.
  * If MIN-MAX condition is selected for the Tariff 2, then Max threshold corresponds to Tariff 2 Threshold window, while Min threshold corresponds to Tariff 1 Threshold window. The Counter and Trigger parameters of Tariff 1 are automatically compared to Tariff 2 parameters, with MAX condition selected automatically. Tariff 1 will become active where the measured parameter value is lower than Tariff 2 Threshold value.  

Important: Where Input 1 (2) is selected in Tariff 1 (2) Threshold, the selected Pulse input cannot be used for pulse output or reception.

Flow regulation methodology

1. Measure the flow measurement errors in the flow stand (in the standard case, according to  the flow rates nearest to qi, 0.1qp and qp). Perform error measurement in the Test mode (Test – by activating it with button ON Test (V pulses) mode, or Service – by activating by shorting the SERVICE contacts). The enlarged resolution content measured can be read on the LCD or calculated according to the sum of the meter’s optic content pulses.
2. Activate the Adjustment mode (by shorting the ADJ contacts – the wing symbol should appear on the LCD).
3. Read the meter configuration (press Read configuration).
4. Enter the flow errors measured in percentages in the windows next to the nearest flow values measured, in the Err[%] table column of the Adjustment / Flowrate window.
5. Press Calculate button in the programme window.
6. Enter the configuration into the meter (press Write configuration).

Temperature regulation methodology

1. Measure the measurement error of the meter’s minimum temperature difference. To accomplish that, submerge both temperature sensors into the calibration thermostat with the measured standard temperature To. Read the results of the measured temperature differences dT (T1-T2) on the meter’s LCD. Perform error measurement in the Test mode (Test – by activating it with button ON Test (V pulses) mode, or Service – by activating by shorting the SERVICE contacts).

2. Activate the Adjustment mode (by shorting the ADJ contacts – the  symbol should appear on the LCD).

3. Read the meter configuration (press Read configuration).

4. Read the values of calibration parameters R2lo and R2hi in the Adjustment / Temperatures window.

5.  Calculate the new values of calibration parameters R2lo and R2hi according to the measurement results in section 7.1.

6. R2lo‘= R2lo + dT · 1,925

7. R2hi‘= R2hi + dT · 1,925
   Enter the new R2lo and R2hi values into the respective programme windows.

8. Enter the configuration into the meter (press Write configuration).

Clock error correction methodology

1. Measure the meter clock measurement error – by reading the time displayed on the LCD, register the clock measurement gain (+ Δt, sec) or loss (-Δt, sec) per time period within N days. The time measurement error is calculated as follows: dt = Δt / (N · 24 · 3600) · 1000000, ppm
2. Activate the Adjustment mode (by shorting the ADJ contacts – the <-> symbol should appear on the LCD).
3. Read the meter configuration (press Read configuration). Read the time correction parameter k Clock correction, ppm in the Adjustment / Temperatures window.
4. Calculate the new value of the time correction parameter:  k‘ = k – dt and enter it into the programme window Clock correction, ppm.
5. Press Correct clock.
