The LD31 Series DeltaSpan consists of a piezoresistive sensing element, encased in
316 SS housing. Superior lightning and surge protection utilizing dual arrestor
technology, grounded to case, eliminates both power supply surges and lightning
ground strike transients. Bullet nose design protects diaphragm from damage.
The LD32 Series DeltaSpan consists of a piezoresistive sensing element, encased in
316 SS housing. It is perfect for wastewater and slurry applications with features to
protect the unit from these demanding applications. Superior lightning and surge
protection utilizing dual arrestor technology, grounded to case, eliminates both power
supply surges and lightning ground strike transients. Large diameter 316 SS
diaphragm seal is non-clogging and damage resistant to floating solids.
Both units come equipped with a 270-pound tensile strength, shielded, vented cable.
Ventilation tube in the cable automatically compensates for changes in atmospheric
pressure above the tank. The vent tube has a filter attached to the end that will block
particles, such as dust, dirt, and water droplets, from entering the tube.
This Quick Start includes everything you’ll need to get the DeltaSpan up and running.
For complete information, please refer to DeltaSpan documentation located at
www.flowline.com.

10 28’ / 7.4M
15 34’ / 10.5M
20 46’ / 14.0M
Electrical Installation
An external power supply delivering 13-30 VDC with minimum current
capability of 40 mA DC (per transmitter) is required to power the control
loop. The Current Output diagram (shown below) shows the connection of
the power supply, transmitter and receiver.
The maximum receiver load resistance (RLmax) for the DC power supply
voltage (Vsup) is expressed by the formula: RL Max = V sup - 13V
0.02A
Shielded cable should always be used for control loop wiring.
Maximum Loop Resistance is 850 ohms @ 30 VDC.
Troubleshooting
If you face any issues not addressed in this quick start, please refer to the
DeltaSpan Manual located on Flowline website at www.flowline.com.
Safety Concern
Where personal safety or significant property damage can occur due to a spill, the
installation must have a redundant backup safety system installed.
Welcome to the DeltaSpan Quick Start
The DeltaSpan Quick Start is meant to show some of the more common setup solutions
to getting the DeltaSpan up and running quickly. If you run into an issue that is not
addressed here or wish to install or set up with a non-standard configuration, please
address the DeltaSpan Manual or refer to the Flowline website at www.flowline.com.
