    Abstract: In one example in accordance with the present disclosure a device for coalescing a frothy fluid is described. The device includes a housing and alignment devices. The alignment devices receive a number of coalescing filters, space the number of coalescing filters to form a gap between adjacent coalescing filters, and seal the number of coalescing filters against the housing to enclose the gap. The device also includes an inlet port to drive incoming frothy fluid through the gap, an outlet port to drain coalesced fluid, and an air vent to allow air to escape the gap.

    Abstract: A froth coalescing unit for a fluid delivery system for a fluid ejection system, the froth coalescing unit including a coalescing chamber including a sump, an inlet to receive froth into the coalescing chamber, the froth comprising a mixture of fluid and gas, the coalescing chamber to coalesce the fluid from the froth with the coalesced fluid collecting at least in the sump, an outlet to communicate coalesced fluid from the sump, and a fluid level sensor to provide a level over a range of levels of coalesced fluid in the coalescing chamber including in the sump.

    Abstract: In one example, a fluid property sensor includes an electrical circuit assembly (ECA), an elongated circuit (EC), and an external interface. The EC is attached to the ECA and includes multiple point sensors distributed along a length of the EC. The external interface is electrically coupled to a proximal end of the EC. The EC and the external interface are packaged together with an encasement on both sides of the ECA to form the fluid property sensor.

    Abstract: In one example in accordance with the present disclosure a device for coalescing a frothy fluid is described. The device includes a housing and a filter disposed within the housing. An outside surface of the filter is separated from an inside surface of the housing by a gap. The filter is sealed against the housing to enclose the gap. An inlet port of the device drives incoming frothy fluid through the gap. An outlet port of the device drains liquid coalesced as bubbles in the frothy fluid dissipate and an air vent allows air to escape the gap.
