Collection:Flow Measurement And Control

Flow measurement and control products cover flow meters, flow switches, flow indicators and flow accessories for liquids and compressed air. Flow indicators show through a window whether water or a water-based liquid flows. They need no power supply and give no value in l/min. They come as sight glass flow indicators in brass or polycarbonate.

Flow meters show the flow rate. Variable area flow meters show it on a scale and need no power supply. Electronic flow meters show it on a display or send it as a signal to a control system. The flow meters are sorted by measuring principle, such as variable area, paddle wheel, magnetic and thermal flow meters.

Flow switches give an electrical signal when the flow reaches a set value, for example to protect a pump against dry running or to monitor a cooling or lubrication circuit. They are sorted by principle and medium: metal variable area, inline and insertion paddle, calorimetric for water-based liquids and thermal for compressed air. Variable area flow meters with switch contact, calorimetric flow meters and thermal compressed air flow meters are listed under both flow meters and flow switches.

The flow meters also include the sensor fittings and transmitters of modular Bürkert flow meters, under Bürkert flow meter components. Flow accessories hold replacement sight glasses, the replacement reed contact for paddle switches and a power supply for compressed air flow meters; Bürkert replacement fittings and transmitters are under Bürkert flow meter components.
