OPERATING DATA MEASURING RANGESOperating pressure, max. 15 bar Water Pressure drop refer to tables on pages 6 and 7 0,05 l/h - 1000 l/h refer to tables on pages 6 and 7 The specified measuring / switching ranges are valid for water having a density of 1.00 kg/dm3, vertical installation of the device and flow direction from bottom to top. Other installation positions or deviation from the operating densities, will increase the measurement error specified in the data sheet. Operating density for water at 20 °C and 1.013 bar abs: 1.00 kg/dm3. 1 Nl/h - 30000 Nl/h refer to tables on pages 5 and...

REGULATOR RCA The design of the series 2000 flowmeters enable the use of RCA or RCD type controllers, which maintain a constant flow, even at fluctuating pressure. Type RCA is used for gases and liquids with variable inlet pressure and constant outlet pressure. FUNCTIONAL PRINCIPLE The media flows, with variable input pressure P0, through the connector (1), past the regulating valve (2) into the regulator chamber (3), where light pressure is exerted on the diaphragm (4). The regulating valve, which is connected to the diaphragm (4), is held open by force of the spring (5). When the media...

REGULATOR RCA FLOW CURVES The flow curves show the relationship between the inlet pressure P0 and the counter pressure P2 in the RCA regulator. The different flow rates are adjusted by means of the regulating valve (7) of the flowmeter. The counter pressure P2, in this cases, corresponds to the atmospheric pressure.

REGULATOR RCD The design of the series 2000 flowmeter allows the use of RCA or RCD type regulators, which maintain a constant flow, even when pressure fluctuations occur. RCD type regulators are used in applications for gases, where the inlet pressure is constant and outlet pressure is variable. FUNCTIONAL PRINCIPLE RCD type regulators operate reversely from RCA type regulators. The change in position of the valve (2) depends on the outlet pressure and the set value on the control valve (7).
