The Smart Pump Assistant App was created to provide ABEL customers with a more user-friendly mobile version of the Online Smart Pump Assistant Dashboard. It allows you to monitor the overall status of your pumps, as well as get insights into several important pump values. ย  If and when anomalies occur, the S.P.A. App will notify you, and tell you โ€ขย ย ย  at which component of the pump the anomaly occurs โ€ขย ย ย  how high the efficiency loss is โ€ขย ย ย  recommendations/instructions on how to fix the issue or receive additional help. ย  With our intelligent algorithms, we will soon be able to predict when an anomaly may occur, and inform you beforehand, greatly reducing or even eliminating the amount of time your pump may be at a standstill.

Which drill bit for a #8 screw in hardwood? ScrewGuide answers in two taps โ€” the complete screw, bolt and drill-bit chart with the exact pilot hole for the material in front of you, fully offline. Printed charts give you one number and hope you guessed the material right. ScrewGuide is material-aware: pick a screw, pick softwood, hardwood, MDF/chipboard, drywall, sheet metal or plastic, and it works out the pilot, clearance and countersink diameter for that exact combination โ€” then names the nearest real drill bit you actually own, in millimetres or inches. WHAT YOU GET - The right pilot hole every time, calculated per material, so boards stop splitting and screws stop stripping - 20 screw sizes cross-referenced: metric M2-M12, US gauge #4-#14 and tapered wood screws, with major and minor diameter, thread pitch, TPI, head diameter and typical lengths - A full 68-bit drill chart in one place: metric, fractional, number and letter bits with decimal and millimetre equivalents - Measured something and don't know what it is? Dial in a diameter and get the nearest screw and the nearest drill bit instantly - A metric tap-drill chart, so you can thread a hole without hunting a reference online - Head styles and drive types decoded โ€” Phillips, Pozidriv, Square/Robertson, Torx and hex โ€” plus why pilot holes work at all PERFECT FOR - Woodworkers and carpenters who refuse to split another board - DIYers assembling flat-pack, hanging shelves or mounting a TV - Makers and 3D-printing hobbyists living in M3 and M4 hardware - Trades and hobby mechanics switching between metric and imperial on the same job WHY NOT JUST GOOGLE IT? Because the garage has no signal, your hands are dirty and the search results argue with each other. ScrewGuide keeps every number on the device, opens instantly, and gives one clear answer per material instead of ten forum opinions. Save the sizes you use most and they are one tap away next time. PRIVACY No account, no sign-up, no ads, no tracking, no internet connection required. Your saved sizes and unit preference stay on your iPhone. FULL ACCESS Material-aware pilot, clearance and countersink sizing, the complete drill-bit chart, the tap-drill chart and the size finder unlock with full access. Choose a weekly or yearly subscription, or pay once for lifetime access โ€” one payment, no renewal. Ten common screw sizes stay browsable for free so you can try the reference first. Open ScrewGuide before the drill comes out and get the hole right the first time.
