A flow show is a monitor used in the drilling industry to monitor drilling fluid flow, ensuring safety and rig integrity. It can detect high or low pressure zones and is connected to the flow line, using a scoop to measure flow and provide accurate readings to operators.
A flow show is a type of monitor used in the drilling industry on a rig. Allows operators and users to monitor drilling fluid flow. This is how it got its name “flow show”. Monitoring the flow of fluid being drilled is very important for several reasons, including safety for both personnel working with the rig and the integrity of the rig itself.
If the flow show lets a drill operator know that a high pressure zone is releasing too much fluid at once, overfilling the well, the problem should be addressed immediately. Without monitoring, the flow can become critical and cause damage to the rig. It could also injure workers near the well. This type of problem can cause a business to lose the asset it is trying to extract and can cost a lot of money.
The opposite problem can also occur when drilling. A flow show can tell an operator if a low pressure area is no longer drawing fluids from the well. This is another serious problem that needs to be fixed. If this is not addressed, the pressure could become so low that the borehole and drilling platform could collapse. This will obviously be very expensive for the business, and is a situation to be avoided.
On a rig, the flow show is usually connected to the flow line. This is a hose that sends drilling fluid to mud tanks, which are tanks designed to safely hold drilling fluid. The mud tank is usually dug into the ground near the drilling site and lined with steel. It has an open top so that drill operators can monitor the liquid level in the pit. Offshore rigs may have an enclosed roof, but will still have ways for employees to monitor fluid levels.
When connected to these other fixtures, a flow show will use a scoop to measure the flow of drilling fluid as it passes through the flowline to the mud pit. The flow show is then able to provide accurate readings to rig operators. The vane angle is what gives them this information: if the vane angle is high, the flow is stronger, and if the angle is lower, then the flow is going slower.
