CT5-S20M : 20mm totaliser positive displacement flowmeter with high rate 72 or 121 pulses/Litre output
The CT5-S20M (TD8) 20mm Manifold water meters are suitable for measurement of water up to 30 C continuously (and up to 50 C for up to 2 hours) with a working pressure up to 1500 kPa. The meter offers great accuracy and a long operating life for domestic drinking water applications.
The mechanical counter register is positioned for easy reading and displays from 0.02 to 9,999,999 Litres. The precision engineered rotary piston measuring chamber ensures accurate measurement even at very low starting flow rates. Meters can be installed in any position without affecting accuracy and require no onsite calibration. An inline filter element prevents blockages and an internal check valve located in the manifold section stops backflows.
CT5-S20M Manifold flowmeters are fitted with a high resolution reed switch contact closure output. At the request of various water authorities, with ManuFlo technology, 72 or 121 pulses per Litre (ppL) output signal is achieved (depending on flow measurement chamber used), which is the highest amount of pulses per Litre for a domestic water meter of this size (whilst retaining the mechanical register). This allows capture of precision water measurement information to data-loggers and to other data collection devices. Very accurate data can then be obtained for water usage totals and flowrate habits of consumers. Electrical connection is via a 1.5 metre 2-core shielded cable.
All meters are of MANIFOLD design which screw down on to a manifold coupling of 1 1⁄2”, the manifold has 3⁄4”bsp (male or female entries) with a service gate valve inbuilt (NOTE: Not supplied by ManuFlo). CT5-S20 flowmeters are an adaptation of Aquadis+/TD8 flowmeters, which are manufactured from high quality materials to meet Australian and international Municipal Water Authorities specification requirements for residential water billing purposes.
