Abstract: A data recording and annotation system includes data recording device for generating a data record. After the data recording device receives a request to review the one or more data records, the data recorder provides the one or more data records to the requester. After the data recorder receives an approval or annotation made about the data record, the data recorder generates a revised data record including information from the data record and from the approval or annotation. Then the revised data record is stored on the data recording device. The data records may be accessed at either the data generating device itself, or through a remote connection.

Abstract: Systems, apparatuses, and methods provide for a magnetic inductive flow sensor including a housing with an internal passage. A pair of electro-magnets are positioned within the housing on opposite sides of the internal passage to generate a magnetic field when charged. A pair of electrodes are positioned within the housing on opposite sides of the internal passage to detect a voltage representative of a change in the magnetic field as fluid flows through the internal passage. A first temperature sensor is positioned within the housing. The first temperature sensor detects a first value representative of a first temperature of the fluid. The first temperature sensor is composed of a positive temperature coefficient material. A second temperature sensor is positioned within the housing. The second temperature sensor detects a second value representative of a second temperature of the fluid. The second temperature sensor is composed of a negative temperature coefficient material.
