9.1 Probe Placement
CAUTION: Model 924B and DMP probes must be installed as shown in this
section. If the installation cannot be done with the minimum or maximum
dimensions specified, do not continue with the installation.
Model 924B and DMP probes are safe for Class 1, Div 1, Group D hazardous
locations. This includes tanks containing regular, super, diesel and unleaded
gasoline; antifreeze; kerosene; mineral spirits; oxinol, methanol and methanol
blends; motor, torque and transmission oil; and alcohol. If you are not sure if a
product is included in this class, speak to your product specialist or distributor.
The best location to install a probe is in the center of the tank (see the illustration below).
The probe must be installed (approximately) a minimum of three (3) feet (91 cm) from the tank fill-pipe. If the
distance is less than this interval, the force of the product that goes into the tank can cause the water float to
travel up the shaft of the probe. This can cause the controller to give an incorrect high-water alarm.
Adjust the drop-tube of the fill pipe so that the product flow is pointed away from the probe.
A Submersible Turbine Pump (STP) must be installed (approximately) a minimum of three (3) feet (91 cm)
from the probe. If the distance is less than this interval, the force of the product that the pump pulls from the
tank can cause incorrect indications of the water and product floats.
