Differential Pressure Flowmeter

The DDM orifice is designed to measure and control the flow of liquids and gases.The differential pressure at the orifice is proportional to the square of the volume rate of flow through the pipeline. The DDM-DN orifice is fitted between flanges in the pipeline. The DDM-Rp/Gi/Ga orifice is installed in the pipeline using pipe unions or with either internal or external thread. download pdf datasheet

The DDM-DS11 metering orifice measures and monitors the flow rate of liquids. The device works according to the principle of differential pressure. The DS11 gauge contains a rugged and uncomplicated diaphragm system. The differential pressure generates a unilateral force at the membrane which moves the diaphragm system against the measuring range springs. download pdf datasheet

The DDM-EM metering orifice measures and monitors the flow rate of liquids. The device works according to the principle of differential pressure. A tough and insensitive sensing diaphragm is embedded in the EM-transmitter housing. download pdf datasheet

The DDW-DS31 flow monitor is used for monitoring the flow of water, oils, and neutral liquids. The DS31 flow monitor contains a rugged and uncomplicated diaphragm system. The differential pressure generates a unilateral force at the membrane which moves the diaphragm system against the measuring range springs. The resulting displacement activates a micro switch. The user sets the switch locally by a hand wheel in the range of 30 – 100% of the flow span. download pdf datasheet

The Kirchner Bypass Flow Meters DST for water, aggressive media, air and gas are used for large flow rates. Easy installation of the orifice plate in any position, the scale is specific to the liquid, wide choice of materials, no el. power required. download pdf datasheet

The sprinkler measuring orifice SMB is used for flow measurement in stationary sprinkler systems. The device works according to the principle of differential pressure download pdf datasheet
