Descriptions
Fluidwell D077 Panel Mount Level Monitoring is a versatile, panel mount level monitor with linearization and continuous level monitoring features. In addition to the average Span, eight linearization points can be entered to compensate for the tank shape. The unit will interpolate between these points to increase accuracy. This linearization affects all displayed information as well as the alarm output. With the level monitoring feature, one low-level and one high-level alarm value can be set.
Display
The display has large 17mm (0.67”) and 8mm (0.31”) digits which can be set to show level, height, or percentage and alarm values. The display is a transflective type, which means that a high contrast reading is guaranteed, even in full sunlight. The D077 has a smart display update function incorporated. Related to the lower temperatures, the update frequency of the LCD is tuned automatically to achieve a readable display even at -40°C / -40°F.
Backlight
The white backlight in combination with the D077 offers a unique feature: in case of a level alarm, the backlight can be set to be red or flashing red. The intensity can be adjusted in the configuration menu.
Configuration
All configuration settings are accessed via a simple operator menu which can be password protected. Each setting is clearly indicated with an alphanumerical description, which avoids confusing abbreviations. Once familiar with one D-series product, you will be able to program all models in all series without a manual. All settings are safely stored in EEPROM memory in the event of sudden power failure.
Alarm output
One alarm output is available to transmit the level alarm. It can be set to switch for low, high, or both alarms! The output signal can be a passive NPN, active PNP, or a robust, highly isolated electro-mechanical relay (NO/NC).
Fluidwell D077 Panel Mount Advantages
- Unique, robust IP66, IP67 (NEMA Type4X) panel mount front enclosure made of die-cast aluminum, allowing even big water jets and total immersion.
- Familiar with easy operation with the Fluidwell “Know one, know them all” configuration structure, saving time, cost and aggravation.
Features
- Displays level, height, and percentage filled.
- Eight-point linearization of the tank shape – with interpolation.
- Two-alarm values can be entered: low and high-level alarms.
- Level: six large 17mm (0.67) digits.
- Selectable on-screen engineering units; volumetric or mass.
- Auto backup of all settings.
- Ambient temperature: -40°C to +80°C (-40°F to 176°F).
- Red flashing LED backlight in case of a level alarm.
- Aluminum DIN front panel of 144 x 72mm (5.67” x 2.83”) according to DIN 43700 / IEC 61554.
- Various accessories are available for this product.
Applications
- The D077 fits in level measurement applications where continuous level monitoring and linearization of the tank shape is important.
- The D-Series is a DIN-sized display and the better alternative for your existing, not waterproof, front panel mount indicators in extreme weather outdoor applications or e.g. in food industries where working environments are often cleaned with powerful water jets.
