A safety kit is provided for use with a flexible hose for interconnecting a portable tank with a another tank to transmit fluids between the tanks. The safety kit includes a control housing adapted for securing to one end of the hose, and a cable support housing for securing to the opposing end of the hose. A valve member is moveable relative to a seating surface for opening and closing flow through the control housing. A cable is provided for positioning within the flexible hose . The cable may be in compression in one embodiment and in tension in other embodiments. If in compression, the cable support housing includes a cable loading mechanism . When the cable is in tension, the trigger moves in response to movement of the cable to close off flow to the flexible hose.

Flexible hose safety kit

An apparatus and method for accurately controlling the amount of NH to be applied to a field by measuring the NH flow rate without condensing or cooling the NH . The system includes a control station on the vehicle with a tachometer A or a GPS system for providing a vehicle speed signal to a control panel . The control panel includes a toggle switch for adjusting the opening or closing of a valve in the flow line to regulate the flow through the system, although the control panel alternatively may automatically control the valve . The vehicle transports a tank containing liquid NH and a tool bar for distributing the NH to the soil. After flowing through the flow meter , the NH is conducted to the soil through a series of hoses, fittings, a distributor, and tubing. The flow meter transmits a signal to the control panel, which is converted to a corrected flow rate signal in response to a fixed value vaporization correction factor. The temperature of the NH is also measured to correct for density variations. An improved variable area meter uses a hall effect sensor and a magnet mounted on a rotatable vane shaft to overcome problems with prior flow meters. The improved meter is ideally suited for measuring the fluid flow of a low temperature vaporization liquid, such as anhydrous ammonia, propane and butane.
