A hydrostatic system for measuring the elevation at two spaced locations. A first stand having a multi-leg base includes a toroidal tank slidably mounted on a shaft that extends through a tank central aperture. The legs include a bracket arrangement to permit securing each leg at an acute angle, an obtuse angle or parallel to the first stand. Thus, the tank can be positioned above or below the leg connection to measure high or low levels. A second stand includes a vertical transparent tube marked with linear distance indicia. A flexible hose connects the tank to the tube so that water (or other liquid) in the tank, hose and tube reaches the same level in both tank and tube. Two or more second stand, transparent tube and hose assemblies may be connected to the tank to permit simultaneous measurement of elevation at plural locations. The first and second stands and transparent tube may each be telescoping to increase the range of elevation measurements that can be accommodated.
