A modular removable flow metering assembly for a unidirectional fluid channel having three variations. Each embodiment can use a compact fluid conduit for connecting an upstream fluid flow to a downstream fluid flow. An embodiment uses a unitary dual measurement container having an upstream port opening opposite to a downstream port. The upstream port communicates with an upstream fluid channel with an upstream pressure. The downstream port communicates with a downstream fluid channel having a downstream pressure. A cone shaped differential pressure producer with a flared discharge end is in fluid communication with the downstream fluid channel. A manifold can fluidly connect the upstream and downstream fluid channels, and a customer connection device can receive the upstream pressure and downstream pressure.

Milk meter for measuring a flow rate of a milk flow, provided with an inlet, an outlet, and a liquid flow path from the inlet to the outlet. The milk meter has a measuring chamber and a float in the measuring chamber configured to float on milk. The milk meter determines the flow rate from the level of milk and the milk meter is provided with a magnetic unit for generating a magnetic field and the magnetic field varies in height direction of the measuring chamber, and the float has an electronic measuring unit for measuring the strength of the magnetic field. The measured strength of the magnetic field is a measure of the height at which the float is floating on the milk and the measured strength of the magnetic field is a measure of the flow rate of the milk flow.

Waste water assessment apparatus, a method and a computer program are provided. The waste water assessment apparatus comprises: transceiver circuitry configured to transmit a microwave signal and to receive one or more reflections of the microwave signal; and processing circuitry configured to process the one or more reflections of the microwave signal to determine one or more characteristics of waste water flowing through a conduit.
