Systems and methods for predicting, detecting, and/or mitigating a pipe freeze are provided. A system for analyzing water in a plumbing system includes a sensor that is configured to measure pressure within a pipe in the plumbing system as a function of time, and a processor that is configured to determine a state of water within the pipe by analyzing the pressure within the pipe as a function of time. The state of the water includes a prediction that the water within the pipe will freeze and/or a determination that the water within the pipe has frozen. The sensor is arranged at a first location within the plumbing system that is remote from a second location within the plumbing system that corresponds to the state of the water.

Flow sensors are provided that can monitor flow conditions. The flow sensor includes a gauge that provides a first level of information about flow through the sensor, and an indicator associated with the gauge that can provided a second level of information about flow through the sensor. The indicator might be in the form of a dial that can rotate about the gauge and might include a locked position for monitoring flow and an unlocked position to rotate the dial about the gauge to reposition the dial. A twisted shaft with varying twist rate is provided to convert linear motion to rotational motion for the gauge.

A method for optimizing purge gas of a flare system includes measuring a flow of flare fluids within a flare system to obtain a measured flow value. The flow of the flare fluids is compared to a target flow to obtain a difference between the flow of the flare fluids and the target flow. A control valve is operated to amend a flow of purge gas and the steps of measuring a flow of flare fluids and comparing the flow of the flare fluids to the target flow are repeated until the flow of the purge gas is within a target range. A value of the flow of purge gas is measured and transmitted wirelessly to a control system.

A flow gauge scale assembly includes a first scale and a second scale. The first scale is configured to be disposed in a first radial position on a generally cylindrical flow tube through which a ball can move to indicate a flow rate of a flow of gas. The second scale is configured to be disposed in a second radial position that will be at least partially optically misaligned from the first scale when the flow gauge scale assembly is installed in the generally cylindrical flow tube.

An improved fluid flow gauging device includes a light enhanced acrylic block flow tube to optimize visualization of pressure readings. An LED or other light source is fitted to the top of the flow tube and illuminates a float or bobbin from above to provide more accurate readings, especially in low light conditions such as modern operating rooms. In addition, the light enhanced flow tube provides a mechanical backup in the case of failure of newer electronic systems and visually matches the graphical flow display, simultaneously providing a double-check of the electronic system.

A flow meter for measuring fluid flow in a tubular that includes an obstruction suspended in a path of the fluid flow, and where the obstruction has a conical shape. The obstruction can be conically shaped on its upstream and downstream ends, or can be conically shaped only on its upstream end. When only the upstream end is conically shaped, the downstream end can be substantially planar or shaped like a hemisphere. Optionally, the aspect ratio of the obstruction can be changed by manipulating supports that suspend the obstruction within the flow meter.
