{"product_id":"solinst-3250-levelvent-6","title":"Solinst 3250 LevelVent 6","description":"\u003cp\u003eThe \u003cstrong\u003eSolinst LevelVent 6\u003c\/strong\u003e is the vented member of the Levelogger family. Instead of measuring absolute pressure and correcting it afterwards, the LevelVent 6 uses a gauged Hastelloy® pressure sensor that is open to the atmosphere through a vent tube running up the cable to a surface wellhead. The result is water level data that is already barometrically corrected the moment it is recorded — no Barologger, no compensation step in software, and none of the time lag that comes with pairing two separate pressure records.\u003c\/p\u003e\n\u003cp\u003eThe logger holds pressure and temperature sensors, a 10-year battery, memory for 150,000 data sets and a hydrophobic filter inside a 22 mm x 173 mm (7\/8\" x 6.8\") stainless steel enclosure weighing 190 grams. A Faraday cage design protects the electronics against surges and lightning-induced spikes. Both the logger and the wellhead contain permanent, built-in desiccants and hydrophobic filters that keep moisture out of the vent path and never need replacing — a real maintenance saving over vented systems that use consumable desiccant packs.\u003c\/p\u003e\n\u003cp\u003eAccuracy is ± 0.05% FS typical with resolution from 0.001% to 0.0006% FS, temperature accuracy is ± 0.05°C, and the sensor withstands twice its rated over-pressure without permanent damage. A dedicated backup memory keeps the most recent 20,000 readings independently of the main log. Sampling runs from 1\/8 second to 99 hours in linear, event and user-selectable schedules with repeat and pause modes.\u003c\/p\u003e\n\u003cp\u003eProgramming and downloads run through Levelogger Software over the Mk3 USB-C PC Interface Cable at 38.4k baud, or 9600 baud with a Solinst USB cable. The Levelogger App Interface, Solinst Readout Unit and DataGrabber all connect directly to the wellhead, so nothing has to be pulled from the well. The LevelVent 6 also works on SDI-12 and MODBUS networks through a Solinst Interface Cable and integrates with LevelSender cellular telemetry.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChoosing a range.\u003c\/strong\u003e The LevelVent 6 is designed for shallow deployments up to 20 m (65 ft) submergence; the M number is maximum submergence depth in metres.\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eFull Scale\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eAccuracy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eResolution\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eM5\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5 m (16.4 ft)\u003c\/td\u003e\n\u003ctd\u003e± 0.3 cm (0.010 ft)\u003c\/td\u003e\n\u003ctd\u003e0.001% FS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eM10\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10 m (32.8 ft)\u003c\/td\u003e\n\u003ctd\u003e± 0.5 cm (0.016 ft)\u003c\/td\u003e\n\u003ctd\u003e0.0006% FS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eM20\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20 m (65.6 ft)\u003c\/td\u003e\n\u003ctd\u003e± 1 cm (0.032 ft)\u003c\/td\u003e\n\u003ctd\u003e0.0006% FS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eWellhead and vented cable.\u003c\/strong\u003e The compact wellhead measures 30 mm x 76 mm (1.2\" x 3.0\"), is built from black Delrin®, nickel-plated zinc and Viton®, carries an IP 64 rating, and is sized to sit inside a Solinst 2\" Well Cap Assembly.
