To ensure proper operation of pressure control is recommended to place the sensor near the pump. 
To compensate the pressure loss in the pipes (proportional to flow) it is possible to vary the pressure set in a linear relation 
with respect to frequency.  

 

It  can perform the following test to verify the correct value of compensation: 
1. install a pressure gauge away from the pressure sensor  
2. open completely the valve 
3. check the pressure gauge  
--> Set the value of 

compensation

. equal to the difference of the values from the two gauges. 

When using a group of pumps, the pressure compensation to be applied to each pump is equal to the total pressure 
compensation (when all the pumps are running at full speed) divided by the number of pumps in the group.

Для обеспечения правильной работы регулятора давления рекомендуется размещать датчик рядом с насосом.

Чтобы компенсировать потерю давления в трубах (пропорционально расходу), можно изменять давление, установленное в 

линейной зависимости по отношению к частоте.

Датчик давления

Компенсация

Максимальная частота двигателя

Минимальная частота двигателя

установленное значение

Можно выполнить следующий тест, чтобы проверить правильное значение компенсации:

1. установите манометр вдали от датчика давления

2. полностью откройте клапан

3. проверьте манометр
-> Установите значение компенсации, равное 

разнице

 значений двух датчиков.

При использовании группы насосов компенсация давления, применяемая к каждому насосу, равна общей давлению.

компенсации давлений (когда все насосы работают на полной скорости), деленная на количество насосов в группе.
