FAQ – flow regulator

What is a flow regulator?

These are devices of various constructions, designed to ensure a constant flow rate of liquid depending on the current height of the liquid column in front of the device, as well as to stabilize flows before and after devices whose effectiveness depends on the flow rate.

How to select a flow regulator?

To make the appropriate selection, the following data is needed:

  • expected discharge rate from the regulator Q [l/s]
  • allowable wastewater head height above the regulator H [m]
  • diameter of the discharge pipe [mm]
  • installation method:at the bottom in a chamber without a sedimentation part
  • to the wall in a chamber with a sedimentation part (min. 35 cm)

Why regulate the flow of water?

The use of flow regulators allows for minimizing risks such as floods or sewer overflows. Additionally, it enables the use of pumps with smaller operating parameters and protects pre-treatment devices from hydraulic overload, which would result in the deterioration of wastewater quality at the outlet.

What is the purpose of each type of regulator?

Flow regulators differ in terms of their specific installation methods, operating principles, performance characteristics, and capacity range. The key aspect that most often determines the choice of a particular regulator model is its capacity. Generally, it can be assumed that conical-vortex regulators are preferred in situations requiring the management of smaller liquid flows, while orifice models are more suitable for larger flows.

What are the key parameters of flow regulators?

  • discharge flow rate Q [l/s],
  • head height before the regulator H [m],
  • diameter of the outlet pipe DN [mm],
  • installation location (at the bottom / to the wall of the well (min. 35 [cm] of the settling part)).

How does a conical regulator work?

The operating principle is based on inducing a swirling flow inside the device. The energy losses resulting from the liquid being set into a swirling motion translate into a natural throttling effect, the intensity of which depends on the pressure of the incoming stormwater.

How does an orifice regulator work?

It operates on the principle of utilizing a specially designed constriction, which is a key element in shaping the liquid flow characteristics. The constriction is responsible for creating hydraulic resistance that controls the flow of the liquid.
