Abstract

The invention comprises an arrangement in a pressurised piping system for a fluid with a pilot controlled valve (1) comprising a main channel, with a membrane valve (6), and a pilot flow channel with a pilot valve (4). The arrangement comprises a flowmeter/indicator (8) for measuring/indicating the pilot flow through the pilot flow channel.
