A [`SensorBase`](https://rapi.sleaze.dev/classes/SensorBase.md) that outputs [`Force`](https://rapi.sleaze.dev/classes/FluidForceSensor.md), [`Torque`](https://rapi.sleaze.dev/classes/Torque.md) and [`CenterOfPressure`](https://rapi.sleaze.dev/classes/FluidForceSensor.md).

## Properties

### CenterOfPressure

```luau
FluidForceSensor.CenterOfPressure: Vector3 = Vector3.zero
```

- Tags: Read only, Read capabilities: Basic, Save only, Simulation access

Assembly center of pressure offset from its center of mass in world coordinates.

### Force

```luau
FluidForceSensor.Force: Vector3 = Vector3.zero
```

- Tags: Read only, Read capabilities: Basic, Save only, Simulation access

Assembly fluid force in world coordinates.

### Torque

```luau
FluidForceSensor.Torque: Vector3 = Vector3.zero
```

- Tags: Read only, Read capabilities: Basic, Save only, Simulation access

Assembly fluid torque in world coordinates.

## Methods

### EvaluateAsync

```luau
FluidForceSensor:EvaluateAsync(linearVelocity: Vector3, angularVelocity: Vector3, cframe: CFrame): ...any
```

- Tags: Yields, Capabilities: Basic, Simulation access

Asynchronously computes force, torque, and center of pressure for the parent part of a sensor given provided inputs.

Parameters:

- `linearVelocity`: Linear velocity in world coordinates.
- `angularVelocity`: Angular velocity in world coordinates.
- `cframe`: [`CFrame`](https://rapi.sleaze.dev/index/types/CFrame.md) to be used for evaluation.

Returns: Tuple of [`Force`](https://rapi.sleaze.dev/classes/FluidForceSensor.md), [`Torque`](https://rapi.sleaze.dev/classes/Torque.md) and [`CenterOfPressure`](https://rapi.sleaze.dev/classes/FluidForceSensor.md) calculated given the input parameters.
