Pick the sensor and the device it goes on; the node and hub use different connectors, so the \"for\" in each name matters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTank level.\u003c\/strong\u003e A stainless submersible sensor on a 15 ft cable with a 15 ft extension (30 ft total), reading 0 to 100 percent of any tank you calibrate it to. We recommend the submersible for every tank; the only chore is wiping it down when you clean the tank. The ultrasonic sensor with its mounting bracket is for open-top tanks on an electric releaser (15 ft cable, no extension).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVacuum.\u003c\/strong\u003e A digital sensor for the Universal Sensor Node, 0 to 29.9 inHg. Put one at the end of each mainline and the app shows which line dropped. For vacuum at a Sensor Hub, nothing to add: the hub has its own.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePressure.\u003c\/strong\u003e Digital, for the Universal Sensor Node. 0 to 725 PSI watches your RO, or a transfer line that is building pressure because it froze. -14.5 to 14.5 PSI reads the level of a tall silo tank (up to 33 ft) and, paired with a vacuum sensor at the top, the level of a vacuum tank.\u003c\/p\u003e\n\u003cp\u003eWater meters are their own product: \u003ca href=\"\/products\/water-meters\"\u003eWater Meter, Universal Node compatible\u003c\/a\u003e.\u003c\/p\u003e","brand":"SapSpy","offers":[{"title":"Tank level, submersible, for Universal Node","offer_id":67704396808352,"sku":null,"price":240.0,"currency_code":"USD","in_stock":true},{"title":"Tank level, submersible, for Sensor Hub","offer_id":67704396841120,"sku":null,"price":240.0,"currency_code":"USD","in_stock":true},{"title":"Tank level, ultrasonic, for Sensor Hub (open-top tanks)","offer_id":67704396873888,"sku":null,"price":240.0,"currency_code":"USD","in_stock":true},{"title":"Vacuum, for Universal Node","offer_id":67704396906656,"sku":null,"price":90.0,"currency_code":"USD","in_stock":true},{"title":"Pressure, 0 to 725 PSI, for Universal Node","offer_id":67704396939424,"sku":null,"price":200.0,"currency_code":"USD","in_stock":true},{"title":"Pressure, -14.5 to 14.5 PSI, for Universal Node","offer_id":67704396972192,"sku":null,"price":200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0491\/8303\/1456\/files\/sensors-trio_7300ebf1-1f7c-47b5-a995-cfc859114a0d.png?v=1792091992","url":"https:\/\/sapspy.com\/products\/sensors","provider":"SapSpy","version":"1.0","type":"link"}
