BS-PTM61-WiFi - Controlling a pump in a borehole or well to monitor and fill a reservoir

The BS-PTM61-WiFi (Pump Tank Management) controller is your go-to solution for expertly managing the filling of a tank. It seamlessly controls a pump located in a borehole or well, ensuring precision and efficiency in every operation. It keeps an eye on as many as 3 liquid levels in the source and another 3 levels in the vessel.

The device runs seamlessly on a 220V AC (85V-240V) mains supply, ensuring uninterrupted operation. It can be manufactured upon request in either 12V or 24V DC configurations. Available in two versions: one with a graphic display and one without. It’s securely mounted on a DIN Rail alongside an external fuse, contactor, or soft start module, specifically designed to match the pump’s power requirements. The BS-PTM61-WiFi serves multiple functions:

For the water level in a well or borehole, inputs for three sensors are provided, displayed in the left column of the front panel with three LED indicators with traffic light colors, convenient for monitoring from a distance. Four liquid levels are indicated: minimum level (three off), low level (illuminated red), medium level (illuminated red and yellow), maximum level (illuminated red, yellow and green). A configuration with two sensors for minimum and maximum level, with a missing sensor for medium level, is possible. Configuration settings for available sensors via a smart device.

For water level in the tank, inputs from three sensors are provided, displayed in the right column of the front panel with three LED indicators with the colors of the traffic light. The level indication is the same as the left column. A configuration with only two sensors for minimum and maximum tank level is possible.

For each level input, the type of contact can be defined – open or closed when liquid is present. The distance between the water column level sensors is determined by the customer according to the specific needs of the site.

Interpretation of indicators:

Two-color LED on the left, above the display.

The operating screens scroll automatically every 8 seconds to indicate all the necessary information for the observer or operator of the device.

The following information is displayed on 8 consecutive screens:

During pump operation, the automatic scrolling of the screens is replaced by visualization of the pump cycle with highlighting of the time in the format: Hour:Minutes:Seconds with an accuracy of one second.

In the case of a device without a display, the information is available on the screen of a smartphone, tablet or laptop. The QR code on the front panel leads to the portal for data from our loggers.

The controller has no visible buttons on the front panel. All settings and control are performed via a smart device with WiFi or via a local network to which it is already connected.

To connect to the device, you do not need a special application, a web browser is used. The home page displays the indicators, as arranged on the front panel, indicating the water levels in the borehole/well and tank. Between them, an animation of the pump is inserted if it is turned on. This is followed by statistics on the pump cycles for the day, week and month, as well as information about the network, device name, installation location, owner name and clock set via the Internet.

Manual pump switching mode is activated via smartphone by clicking on the green button labeled "Automatic". The device switches to "Monitor" mode. The operator can choose when and for how long to turn the pump on and off with the "Pump On/Off" button, without the controller observing the programmed times for the duration of the pump cycle and pause, as well as without protecting the well from complete pumping below the minimum level. By clicking on the "Monitor" button, the "Automatic" mode is returned.

Pumping a well below the minimum level is possible without the need for a smartphone via an external button connected to the controller.

When the controller is set to connect to the local WiFi network of the site, each event is transmitted to the data server. The client monitors the change in the levels in the borehole and the tank, as well as each start and stop of the pump, through a user account with a name and password. Events are marked with date and time with an accuracy of up to a second.

To track past periods, the client has a calendar. The data is visualized in tables and graphs. Each pump cycle is marked with a red field START and a blue field STOP, accompanied by the duration of operation. When the pump power is entered in watts, the site calculates the power consumed for the selected period in kilowatt/hour.
