Embodiments of the present disclosure provide for weight measurement of grow towers and/or grow lines with grow towers disposed thereon. In various embodiments, compression type, tension type, and/or beam type load cells may be positioned at various locations within the apparatus to facilitate weight measurement. In one embodiment, a hook, which couples a grow tower to a grow line, includes a tension type load cell disposed between two portions of the hook. The load cell measures force applied thereto which can provide or be translated into a weight measurement.

A fluid container measurement system is disclosed. The fluid container measurement system is configured to suspend a load measurement assembly a distance above a support surface. The load measurement assembly houses a load cell and a measurement control circuit. The measurement control circuit is coupled to the load cell and configured to receive electrical signals indicative of a force imposed on the load cell. Electrical signals generated by the load cell indicative of the force exerted on the load cell can be used to measure the fluid container attached to the load cell linkage member.

An output-torque estimation unit obtains a value of a current input to a motor, from a power converter, and calculates an estimated output torque value which is an estimated value of output torque of the motor, from the obtained value of the current. A load estimation unit estimates a load value of a hanging cargo based on the estimated output torque value which is calculated by the output-torque estimation unit, a speed reduction ratio of a speed reducer, an effective radius of a winch drum, and the winding number which is set by the number setting unit.

A method to automatically calibrate a load cell without the need to remove the loading on the load cell. This method takes advantage of the fact that weight stack strength equipment uses generally known discrete weight increments, and any signal drift in the load cell can be automatically recalibrated by offsetting the load cell signal to accurately reflect the expected discrete weight increments without the need for unloading the load cell and without the need for a manual recalibration of the load cells.

A mass measurement device comprises a force sensor, a hose, a base part, an article-holding part, and a computation unit. The force sensor has a fixed end and a free end, and outputs a sensing signal in accordance with the magnitude of a force in a sensitivity direction. The hose is configured to pass suctioned air through it. The fixed end is fixed to the base part. The article-holding part is fixed to the free end, one end of the hose is connected to the article-holding part, and the article-holding part holds an article by air suction. The computation unit computes the mass of the article based on the sensing signal.
