DIGITAL TANK LEVEL GAGE displays liquid level and alarms if is out of range.
Liquid level gage for tanks displays the level in the tank with a bar graph and numerical display.
The sensor responds to changing liquid level by indicating with a bar graph and numerical reading. It can work using either a radar sesnor or a submersible pressure sensor.
There are four independent alarm points that can be configured many different ways. For example there could be a H, HH, L and LL events. These are indicated with the LEDs on the panel. In addition the stack light will indicate all of these in any order. For example the yellow stack LED could indicate only the H alarm. In addition, any of the action points can generate another signal for other actions like a text message or email, or communication to a building alarm system.
SENSORS
Radar sensor is the preferred sensing technology. We don’t deal in unreliable ultrasonic sensors, or other technologies. Radar has the advantage that it is non-contact.
Radar sensors measure liquid depth by sending electromagnetic waves of energy down to the liquid surface. The time it takes for the waves to bounce back is directly related to the depth of the liquid. Radar sensors are know for high accuracy and reliability. They are known for their success in challenging environments that might include vapour, gases, temperature variations, extreme temperatures, extreme dust, wind, or foam. This is because the signal reflects best from materials that have a high dielectric constant. In fact, they will even sense through low-dielectric materials like plastics. So if the tank is plastic, then the tank could be monitored without even needing a hole in the tank!
