The technology for a pedometer includes a mechanical sensor and software to count steps. Early forms used a mechanical switch to detect steps together with a simple counter. If one shakes these devices, one hears a lead ball sliding back and forth, or a pendulum striking stops as it swings. Today advanced step counters rely on MEMS inertial sensors and sophisticated software to detect steps. These MEMS sensors have either 1-, 2- or 3-axis detection of acceleration. The use of MEMS inertial sensors permits more accurate detection of steps and fewer false positives. The software technology used to interpret the output of the inertial sensor and "make sense of accurate steps" varies widely. The problem is compounded by the fact that in modern day-to-day life, such step-counters are expected to count accurately on locations where users frequently carry their devices (attached to the belt, shirt/pants pocket, hand bag, backpack)..
2 Inch Dial Face 1/4 Inch NPT Water Pump Pressure Gauge with 1/4 Inch NPT Male 1/2 Inch NPT Adapter Brass Fitting and Tape
NEW GENERATION: On the basis of the drain mode, our Ortis water level controller has added a water mode and 3 load running mode for you to choose, you can manully select the load running mode according to your needs. The Values are clearly displayed with LED indicators, easier to check and set for you.
HI-LO DUAL SENSORS: The hi-lo sensors uses a patented water level detection method, which keeps the electrode intact for 10 years. It is made of 304 stainless steel and is not affected by mineral or water debris. It has strong corrosion resistance and never needs to be cleaned. The height of two sensors is adjustable, you can decrease how often the pump turns on/off by adjusting the sensors in order to save energy and max your pump's service life.
SAFE & STABLE: Ortis pump controller can completely overcome the shortcoming of the tranditional mechanical float switch which is prone to mechanical failure. Long life and small size, no moving parts in pit ensures reliability and is used in various application scenarios, stable and safe.
OVERLOAD & PUMP FAILURE ALARM: When the pump power is greater than 23A, overload protection will be activated to protect your safety. Built-in alarms will alert you in case of pump failure, blocked discharge pipe, and more.
