Now the water saving benefits of detecting leaks, broken sprinkler heads or stuck zone valves are available for smaller systems with lower flow zones. The ELF with proven reliable technology, is easy to install making it easy to conserve water, save money and maintain landscapes.\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eFlow Measurement Range: .20 to 20 GPM\u003c\/li\u003e\n\u003cli\u003e2 Wire Frequency output compatible with most smart irrigation controllers \u003c\/li\u003e\n\u003cli\u003eWorking Pressure Rating: 240 PSI\u003c\/li\u003e\n\u003cli\u003eLED indicator on Sensor\u003c\/li\u003e\n\u003cli\u003eFriction loss at full flow averages 0.20 PSI\u003c\/li\u003e\n\u003cli\u003e1'' Male Pipe Thread Connections\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInstall above or below grade on horizontal or vertical pipe.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eAdvantages of ELF Flow Sensors over Water Meters\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eMeasures a much wider range of flows\u003c\/li\u003e\n\u003cli\u003eOperates without pressure loss\u003c\/li\u003e\n\u003cli\u003eHigher pressure rating – 240 psi\u003c\/li\u003e\n\u003cli\u003eEasy to install, no special fittings required\u003c\/li\u003e\n\u003cli\u003eSimple to clean or service\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInstead of estimating your water usage, accurately measure it in real time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"et_pb_module et_pb_text et_pb_text_0  et_pb_text_align_left et_pb_bg_layout_light\"\u003e\n\u003cdiv class=\"et_pb_text_inner\"\u003e\n\u003cp\u003eThis innovative new design, issued US patent no. 10060774 B1 in 2018, allows this sensor to measure flow rates over a range from .20 to 20 GPM using the proven impeller technology of the other CST flow sensors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"et_pb_module et_pb_text et_pb_text_1  et_pb_text_align_left et_pb_bg_layout_light\"\u003e\n\u003cdiv class=\"et_pb_text_inner\"\u003e\n\u003cp\u003eThe standard sensor output is a digital pulse proportional to flow. The electrical characteristics of the output signal duplicate other two wire digital outputs making this “frequency” output signal compatible with most manufacturer’s “smart” irrigation controller products. The pulse signal will travel up to 2,000 feet without amplification.\u003c\/p\u003e\n\u003cp\u003eThis new design eliminates the need for straight pipe sections up and downstream of the sensor allowing for installation in tighter spaces. In fact, solenoid valves may be connected directly to the downstream end of threaded ELF versions resulting in a flow sensor\/master valve combination less than 12 inches long.\u003c\/p\u003e\n\u003cp\u003eDesigned for the harsh environment of irrigation service, Creative Sensor Technology now warranties all of its sensor electronics with a lifetime replacement guarantee.\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003eOutput Signals\n\u003cul\u003e\n\u003cli\u003eFrequency Range 1 Hz to 150 Hz\u003c\/li\u003e\n\u003cli\u003eOutput Pulse (low) 2 msec typical\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eTransducer Excitation\n\u003cul\u003e\n\u003cli\u003eQuiescent current 330 uA@5 VDC to 35 VDC max.\u003c\/li\u003e\n\u003cli\u003eOn State V(low)= 0.85 volts@ 50mA (max.)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eOutput Leads\n\u003cul\u003e\n\u003cli\u003e2 single conductor solid copper U.L. listed #20 AWG leads with direct burial insulation\u003c\/li\u003e\n\u003cli\u003eLead length 24 inches\u003c\/li\u003e\n\u003cli\u003eWiring may be extended up to 2,000 feet with direct burial, twisted pair shielded cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eDimensions\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eLength: 7.125''\u003c\/li\u003e\n\u003cli\u003eHeight: 3.875'' \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eManuals \u0026amp; Literature\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.creativesensortechnology.com\/wp-content\/uploads\/2025\/05\/ELF-01-Series-Installation-Guide-Rev-E-091423.pdf\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eInstallation Instructions\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.creativesensortechnology.com\/wp-content\/uploads\/2025\/05\/ELF-Sensor-Data-Sheet-RevD-011420.pdf\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eSpec Sheet\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.creativesensortechnology.com\/wp-content\/uploads\/2025\/06\/ELF-SME-Announcement-060925.pdf\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eELF Announcement\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Creative Sensor Technology","offers":[{"title":"Default Title","offer_id":51312388374824,"sku":"ELF-T10-N01","price":125.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0167\/3543\/6900\/files\/elf01.png?v=1767387391","url":"https:\/\/cheapsprinklers.com\/products\/cst-1-elf-series-flow-sensor-enhanced-low-flow","provider":"Cheap Sprinklers","version":"1.0","type":"link"}
