ELECTRICAL INSTALLATION

When routing wires, the AC power must be kept sepa-

rate from the analog output. Do not run the analog out-

put in the same conduit with any AC power or near any

AC wiring or AC conduit. If using several UL transmit-

ters, do not run the sensor cables together. The sensor

cables must be run in separate conduit or interference

may result.

Use 18 AWG shielded two conductor cable for the out-

put signal. Use 16 AWG two conductor cable for the

power and ground. Connect the sensor cable as shown

in figure 1, with the red wire connected to the “TC” ter-

minal, the center of the cable connected to the “CENT”

terminal, and the shield of the cable to the “SHIE” ter-

minal.

NOTE: Do not use the Series UL Ultrasonic Level

Transmitter in applications where foam, agitation or

heavy vapor are present.

GENERAL

The Series UL Ultrasonic Level Transmitter provides

continuous, noncontact sensing for level control of liq-

uids or slurries. The sensor emits an ultrasonic pulse

which is reflected back to the sensor at the liquid/air

interface. The distance traveled by the pulse is calcu-

lated and converted to a 4 to 20 mA output signal.

MECHANICAL INSTALLATION

The sensor should be mounted on the top of the vessel

with the sensor facing down. The sensor face should be

parallel to the surface being measured. A clear path, free

of obstructions must be provided between the sensor

and the liquid surface. Obstructions in the beam path

will cause incorrect readings.

The ultrasonic wave spreads as it travels from the sen-

sor to the target material with the beam angle being 6.5

degrees from the center line. Typically the beam diame-

ter will increase three inches (3⬙) for every foot (1⬘) of

range. For example: An 18⬘deep tank will have a beam

diameter of 54⬙(3⬙⫻18⬘) in diameter at the bottom of

the tank.

A blind zone exists directly in front of the sensor. Liquid

levels cannot be detected in the blind zone. The UL100

has a blind zone of 12⬙, and the UL200 has a blind zone

of 18⬙. If it is necessary to measure to the top of the ves-

sel, the sensor may be raised above the tank with a pipe

or other means. The diameter of the pipe or extension

piece must be greater than 6⬙. Be sure not to mount the

sensor too close to the tank wall.

The Series UL include a 2⬙or 3⬙mounting flange. Sim-

ply bolt the sensor/flange assembly to the proper mat-

ing flange connection. The NEMA 4X control box can be

remotely mounted at a maximum distance of 100 feet

(30 m).

OPERATION

The Series UL is factory calibrated. Do not make ad-

justments on the board except programming English/

Metric, failsafe condition, and desired zero and span.

All programming is achieved through five numbered

BCD turn switches and two slide switches, see Figure 1.

Select english (inches) or metric measurement (cen-

timeters divided by two) using the slide switch marked

“E” or “M.” English (inches) is designated by “E,” metric

designated by “M.” The slide switch marked “H” and

“L” determines the failsafe condition if the echo is lost.

If “H” is selected, the output becomes 21 mA if the

sensor loses the echo. If “L” is selected, the output

becomes 3 mA if the echo is lost.

SETTING ZERO AND SPAN

The span is the distance from the sensor face to the

closest point or level to be measured. This point corre-

sponds to an output of 20 mA. The span must be ad-

justed for a distance greater to or equal to the dead

zone. See Figure 2. The Model UL100 has a dead zone

of 12⬙and the UL200 has a dead zone of 18⬙. Set the

span using a small screwdriver and adjusting the two

BCD switches labeled “SPAN” (Figure 1). The left

switch adjusts in increments of ten, the right switch ad-

justs in increments of one. Example: left switch set at

1, right switch set at 2 corresponds to 12. The zero is

the distance from the sensor to the furthest point or

level to be measured. This point corresponds to an

output of 4 mA. Using the three BCD switches marked

“ZERO,” adjust the zero distance in the same manner

as the span was adjusted. From left to right, the

switches adjust in increments of 100, 10 and 1. Exam-

ple: far left set at 1, middle set at 2, right switch set at

0 corresponds to 120.

LED INDICATION

Apply power to the unit. During normal operation, the

red LED will flash. If the red LED is off, the unit is not

receiving an echo. Check sensor wiring and place-

ment. Be sure the sensor points at the liquid surface

with the sensor face parallel to the liquid. If the red LED

remains on, the unit is receiving out of range echos.

Check tank measurements, reprogram, and check E/M

slide switch for proper setting.

A flashing yellow LED indicates power fluctuations or

the temperature wire is not connected. Verify the red

wire from the sensor is connected to the “TC” terminal.

Also make certain the power source is not shared with

motors or heavy switching loads. All instrumentation

should be on its own power source.

MAINTENANCE

After final installation of the Series UL Ultrasonic Level

Transmitter, no routine maintenance is required. Peri-

odic checks of connections and sensor placement is

recommended. Units are not field serviceable and

should be returned to the factory, freight prepaid, if

repair is necessary. Be sure to include a complete

description of the application and problem.
