CT5-S20 : 20mm totaliser positive displacement flowmeter with high rate 72 pulses/Litre pulse output
The CT5-S20 (TD8) 20mm water meter is suitable for measurement of water up to 30 C continuously (and up to 50 C for up to 2 hours) with a working pressure upto 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 stops backflows (can optionally have dual check-valves).
CT5-S20 flowmeters are fitted with a high resolution reed switch contact closure output. At the request of various water authorities, with ManuFlo technology, 72 pulses per Litre (ppL) output signal is achieved, 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 supplied with a gasket seat coupling connection kit (optional ball seat available for SydneyWater/NSW). CT5-S20 flowmeters are an adaptation of Aquadis+/TD8 flowmeters, which are manufactured from high quality materials to meet Australian and international specification requirements for residential water billing purposes.
The CT5-S20 20mm provides the best pulse output rate for domestic water meters, with 72 pulses/Litre.
