How do you gauge a flow back tank?

To gauge a flow back tank, you typically use a dipstick or a level sensor to measure the liquid level inside the tank. For more accurate readings, you can employ ultrasonic or radar level measurement devices, which provide continuous data on the tank's contents. Additionally, monitoring the inflow and outflow rates helps ensure that the tank is operating within its capacity and can assist in predicting when it will need to be emptied. Always follow safety protocols when accessing and measuring the tank.
