| Definition | The VMCM2 current meter is based on the original VMCM instrument. The original rotors and housing hardware are retained; only the internal chassis and electronics are replaced. The VMCM has two orthogonal cosine response propeller sensors that measure the components of horizontal current velocity parallel to the axles of the two-propeller sensors. The orientation of the instrument relative to magnetic north is determined by a flux gate compass. East and north components of velocity are computed continuously, averaged and then stored on flash memory. Temperature is also recorded using a thermistor mounted in a fast response pod, mounted on the top end cap of the VMCM. The VMCM2 Current Meter is based on the original VMCM instrument. The original rotors, "sting", and housing hardware are retained; only the internal chassis and electronics are replaced. |
