N4

The N4 orifice flow meter fulfils the requirements for treatment and disinfection of swimming and bathing pools (DIN 19 643)

It is suitable for flexible installation positions without loss of accuracy. The meter can also be used for flow monitoring if fitted with optional limit contacts.

Areas of application:

The N4 orifice flow meter is used to measure the flow of clear liquids in closed pipelines. Fulfilment of DIN 19 643 makes the flow meter particularly ideal for treating and disinfecting swimming and bathing pools.

The N4 orifice flow meter is used in the following industries:

  • Building services equipment, air conditioning and heating technology
  • Water and wastewater
  • Swimming pool technology

Advantages of the mechanical flow meter:

  • Simple installation
  • Fulfils requirements for treating and disinfecting swimming and bathing pools (DIN 19 643)
  • Direct visualisation of the flow in the bypass
  • Suitable for flexible installation positions without a loss of accuracy
  • Available at short notice
