A liquid density sensor has a sensing module, a sensing rod and a floating device. The sensing module has a control circuit having computing functions. The sensing rod has a sensing line electrically connected to the control circuit. The floating device has a first magnetic unit and a floating ball mounted therein. The sensing rod is mounted through the floating device and the floating ball. The floating ball has a second magnetic unit. A specific gravity of the floating ball is lower than that of the floating device. The control circuit calculates a liquid density of liquid based on a distance between the first magnetic unit and the second magnetic unit according to a linear formula.

High accuracy liquid density sensor

A thermal mass flow meter includes a housing, a control module, a plurality of probes, a flow calculation circuit, and a heating module. The control module is installed in a containing space. The probes are connected to one terminal of the housing. The flow calculation circuit is connected to the control module, and has a plurality of circuit boards installed in the probes and a plurality of temperature sensing units connected to the circuit boards. The heating module is connected on one of the circuit boards, and connected to the control module. The control module controls the heating module to heat a working fluid in a pipeline; the flow calculation circuit senses the temperature inside the pipeline to acquire temperature change values, and transmits the temperature change values to the control module; and the control module measures the fluid velocity of the working fluid.
