Hydroponic net pot

The specification discloses a DWC hydroponic system that includes a plurality of grow tanks, a circulation pump, a nutrient supply line fluidly connecting the outlet of the circulation pump to the grow tanks, and a tank drain line fluidly connected to the grow tanks. Each of the grow tanks is fluidly connected in parallel between the nutrient supply line and the tank drain line. The system further includes a pump suction line fluidly connected to the inlet of the circulation pump, and a plurality of bridge connectors each fluidly connecting the tank drain line to the pump suction line in accordance with a defined pattern. The DWC system may further include a nutrient supply fluidly connected to the circulation pump intake through a valve arrangement.

Deep water culture hydroponic system

The specification discloses a marine fluid connection system including a fitting and a connector. The fitting is cylindrical and includes a radially extending flange. The connector includes a cylindrical body, a plurality of levers on the body, and a locking ring on the body. The levers are movable between a latched position, in which the levers are closed on the flange to lock the connector on the fitting, and an unlatched position, in which the levers are open so that the connector may be removed from the fitting. The locking ring is axially movable with respect to the body to move the latches between their latched and unlatched positions.

Connector for a fluid handling system

A liquid level sensor for a liquid electrolyte battery is provided. The liquid level sensor includes a probe having a reference electrode and an electrode array. The electrode array includes a plurality of electrodes that are serially disposed in a lengthwise direction of the probe. The reference electrode is capacitively coupled to each electrode within the electrode array, such that the probe provides a capacitance that varies when the probe is immersed in a liquid level that varies in relation to the probe. The liquid level sensor can alert a user of the need to refill the battery or alert a user of the need to refill the battery in the near future. The liquid level sensor can include a series of LEDs that selectively illuminate to indicate each such condition to the user.

Liquid level sensor for battery monitoring systems

An improved battery monitoring system for liquid electrolyte batteries is provided. The battery monitoring system includes a network of sensors for monitoring the condition or performance of a plurality of liquid electrolyte batteries, for example lead-acid batteries. The sensors are adapted to share data regarding battery condition or battery performance to a standalone device over a wireless local area network. A server in electrical communication with the standalone device receives some or all of the data for analysis, which can result in maintenance alerts and other alerts being sent to the standalone device. The improved battery monitoring system can reduce or eliminate the manual inspection of lead-acid batteries and can improve battery operation and longevity by ensuring an appropriate level of maintenance for each lead-acid battery.
