Name the instrument used to measure liquid pressure.

Explanation

**Step-by-Step Solution:**

1. **Understanding Liquid Pressure:**
- Liquid pressure is the pressure exerted by a liquid at a given depth due to the weight of the liquid above it. It acts in all directions and is influenced by the density of the liquid and the depth at which it is measured.

2. **Identifying the Instrument:**
- To measure liquid pressure, we need an instrument that can quantify the force exerted by the liquid against the walls of its container.
