Abstract: A continuous dry particulate matter injection device (1), and more in particular a device for use in a fertigation application in which a soluble matter, such as a fertilizer, is suspended and/or dissolved into the irrigation water in order to use the irrigation system and irrigation water as a delivery system for the soluble matter, in particular a soluble fertilizer. To this end, the device includes at least one feed device (2), suitable for feeding particulate matter, and connected, by a first connection pipe (3), to the top of a vertically positioned slurry mixing chamber (5), located under the first connection pipe (3), and a pressurized mixing tank (12), connected to the bottom of the slurry mixing chamber (5) by a second connection pipe (8). The device is operated in a continuous cycle.

Abstract: An arrangement or provision of a sensor or probe (11) for the measuring of a physical or chemical condition such as pressure, temperature or corrosion in a pipe (1, 2), tank or tubular container being provided with a connection such as a flange connection (3,4) between the pipe, tank or tubular sections. The sensor or probe (11) is provided in conjunction with a gasket such as a ring gasket (8) which is used as a seal between the pipe (1, 2), tank or tubular sections. The probe or sensor element is provided on an inner face of the ring gasket facing the inside of the pipe, tank or tubular sections. Electrical connectors (16) for transforming signals from the probe or sensor element (11) are provided in a bore or bores (14) that stretches from the sensor or probe and through the gasket or ring gasket (8) and to the outside of the gasket.
