8 am - 5 pmBack up pump control is a critical part of any pump control application, ensuring that failure does not result in a potentially hazardous overflow or the unwanted emptying of a tank. Ideally, back up sensors work independently from the control system, so that failure of the primary controls will not disable them.
Rapidly changing liquid levels can overwhelm a single pump, and cause excessive wear and tear. To prevent this, additional pumps can be added to control the liquid level.
Ultrasonic level sensors are great at measuring the distance, or level, of many different material targets. However not all targets are created equal:
With ultrasonic sensors, the most reliable distance readings are obtained when unwanted echoes are reduced or eliminated. This is done when the sensor is set to the minimum power and sensitivities needed to accurately read a target.
Part 4 of our PG10 digital pressure gauge data logging series covers viewing, stopping, and clearing logs. For now, you can access the last 60 data logs via the user-interface on the PG10. However, there is software for full data logging capabilities. Look for that release in the near future. For now, check out the video below:
An abrupt change in a remote tank often spells disaster. These can be due to thefts and leaks or unusual usage patterns resulting in an overflow or a shortage. Even when the change is routine, a notification to verify data is always helpful.
Part 3 of our PG10 digital pressure gauge data logging series covers event-based data logging. This allows you to log certain events based on user-defined criteria. So if you only want to know when the pressure spikes to a certain level, you can. Or you can log loss of pressure. It's entirely up to you! See the video below:
Simplex pump control is a relatively simple task. A float switch with a bit of hysteresis will do just fine. There are, of course, continuous level sensors that may be advantageous under the right circumstances.
