Abstract: A tank suitable for holding a lubricant is provided with a dipstick. A sleeve which is mounted on the tank and adapted to support the dipstick is interconnected with the output duct of the tank by means of a further duct. The arrangement is such that if the dipstick is incorrectly located in the sleeve, air is permitted to flow through the further duct into the output duct so that the pressure of the lubricant in the output duct is reduced. This pressure reduction consequently provides an indication of incorrect dipstick location.

Abstract: A system is described which is useful in dispensing and transferring a predetermined amount of a liquid such as a pesticide from a first container, typically a shipping container to a mixing zone. The control of the total amount of liquid dispensed is achieved by a tubular probe which is slidably mounted in a plug that can be sealed in an aperture of the top or bottom wall of the container. Preferably the probe bears indicia calibrated to indicate amounts of liquid proportional to the depth to which the probe is slid into the container. The device is employed in an system for transferring and metering a toxic liquid such as pesticide in a closed container system wherein the liquid is dispensed and metered from the shipping container and the container is thereafter rinsed free of any pesticide residue in a totally closed system free of any operator intervention.
