Typical Sensor Location Considerations

The sensor mounting location within a space may be dependent on many variables. There are no specific formulas since each application will have it’s own determining factors and priorities. These include, but are not limited to: source of gas: Is the source a combustion exhaust from a vehicle or furnace or a vapour from a tank spill, pipe leak, or faulty valve? density of ...

Giving Valves a Workout

Manual valve exercising is a time-consuming process, and one that poses risks of injury to employees and damage to valves. Valve-exercising technology is designed to automate the process, so that employees do not subject themselves to the strain of turning large or stuck valves, and so that only appropriate levels of torque are applied to valves. Automationhas the added advantage of enabling easy ...
