Description

Liquid-Check SM1 Levelsensor with switch module

Liquid-Check with integrated switching module (3x relay contact + 1-wire connection for 4 temperature sensors)

The electronic measuring system "Liquid Check" enables the measurement of water levels in unpressurized containers. For example, water cisterns, tank contents, etc. By specifying container shapes and dimensions, the conversion into liters is also carried out. The main utility values are therefore, in addition to other information, the height of the water level in meters and the amount of liquid in liters. The measured values are displayed on the digital display on the device as well as via W-LAN connection on a PC or a cell phone. Since the device has a local website, the values can also be integrated into SmartHome systems that support reading values from websites. A program module is available for the open source SmartHome system "FHEM".
The following predefined forms are supported to convert the measured level into liters:
Box, Ball, Cylinder standing, Cylinder lying, Bearing table
Thus e.g. the content of a square basin with the shape "Box" can be captured.
The length and width of the pelvis are then specified in this form function, e.g. "2.4 * 3 * h"

If none of the shapes described fit, a bearing table can be given:
1.       1,0 m     = 300 L
2.       1,5 m     = 450 L
3.       etc. etc.
.          .
.          .
10.     2,0 m     = 550 L

A tank table is usually provided by the tank manufacturer.

Delivery incl. Power supply and fastening material.

Function

How does Liquid-Check SM1 work?

Liquid-Check with integrated switching module (3x relay contact + 1-wire connection for 4 temperature sensors)

The Liquid-Check SM1 is equipped with a switching module which allows a switching process to be triggered at certain fill levels. Furthermore, the LC-SM1 can also switch a switching output via the web interface. The switching relays can be freely assigned to these functions. The device also offers the possibility to connect up to four 1-wire temperature sensors and to display them via the web interface. The switching states and the temperature values can also be called up via http-request.

The measurement method is based on a hydrostatic measurement of the liquid level in a container. Due to gravity, a liquid, depending on its specific density, exerts a pressure on the measuring tube positioned on or above the bottom of a container. By building a back pressure, Liquid Check can determine the corresponding value without being directly in or on the measurement object. Measurements based on the hydrostatic principle always determine the level of the liquid. Using the defined container shape parameters, Liquid Check can also determine the volume content. Liquid-Check does not have to be attached directly to the container to be measured, but can, for example, be installed in the nearby technical room. All that is required for the measurement is a thin hose connection to the container or tank. The end of the hose must be positioned by weight on or above the bottom of the container.

Cloud

Liquid-Check Cloud

Liquid-Check powerd by Grafana

For recording your readings, "Liquid-Check" has an interface to our web portal. Our server uses the visualization software "Grafana". Here your levels and quantities can be stored and displayed graphically (see picture). With your personal login, you have the possibility to monitor the graphics in another location via PC web browser or mobile phone. An alarm level can also be defined, which takes place when the level is exceeded or fallen below. Then it sends a notification by mail.
When you activate the cloud function on the setup page of the Liquid Check, you will receive the access data to the web portal.

Your data is protected by an https connection, as well as by an individual security key.

Once the cloud function is activated, Liquid-Check sends its last measurement to the portal cyclically every hour. In addition, the data is sent to the portal immediately if the measurement is manually activated.

The following data is required for activation:

E-Mail : User's e-mail address

Größe : Maximum amount of filling of the container to be measured

Bezeichnung : Short description of the container e.g. cistern garden

Optionally:

Alarmwert : Filling quantity at which a notification should be made

Benachrichtigung : Notification when the value is above or below

Multiple devices can be managed by activating with the same in one account.

If the cloud function is deactivated in the "Liquid Check" setup page, measurement data will no longer be sent to the web portal. The data that has already been stored is retained in the cloud.

Deleting the cloud account on the "Liquid Check" setup page causes the account to be completely deleted, as well as the recorded measurement data.
