Figure 2-3). The size of the holes will depend on whether

lead inserts are used or the mounting screws are screwed

directly in the wall. Select the appropriate screws and

place the "O" rings on the screws. With a 3/8 inch hex

head driver, secure the back housing to the wall. Since

the power supply board is in the back housing, care

should be taken to prevent damaging any components

on the board. FIGURE 2-3

WIRING CONNECTIONS

The Model 2100 electronics enclosure is provided with

four holes for 1/2 inch NPT conduit fittings. These holes

are on the bottom of the back housing of the enclosure

and allow entry for the 115 (230) VAC power wires,

sensor cable, 4-20 mADC signal output wires and the

relay output wires. Do not run the power wiring, sensor

cable or signal output wires in the same conduit as this

will affect the meter's operation.

The terminals on the power supply board will accept 14

to 22 gauge wire. A small flat blade screw driver will be

required to loosen and tighten the screws. Figure 2-5

identifies the terminals for proper wiring.

Power connections. TB1 is the terminal block for the

115 (230) VAC connections. Terminal 1 is the high side

(black wire) connection. Terminal 2 is the low, or neutral,

side (white wire) connection. Terminal 3 is the earth

ground (green wire) connection.

TB2 Terminals 1 and 2 are the connections for the DC

power input if the meter is to be operated on battery

power Terminal 1 is the positive (+) connection and

Terminal 2 is the negative (-) connection. The DC input

voltage must be between 12 and 14 volts..

When operating the meter on DC power, an additional

DC power source may be required to power the 4-20

mADC output. Refer to the 4-20 mA signal output in the

following section for instructions.

Signal output connections. TB2 is the terminal block

nections for the 4-20 mA output when the meter is

operated on AC power. Terminal 6 is the positive (+)

connection and Terminal 3 is the negative (-) connection.

A jumper wire is connected between Terminals 4 and

5 when shipped from the factory. This jumper must be

in place when operating the meter on AC power.

If the meter is operated on DC (battery) power and a 4-

20 mA output is required, an additional DC power source

may be required. To properly connect the power source

for the 4-20 mA output refer to Figure 2-5. Disconnect

the jumper wire between Terminals 4 and 5. Connect the

positive wire of the battery to Terminal 5, the negative

wire of the battery to the negative input of the load

The wiring connections are marked on the printed circuit

board below the terminal block. Each relay terminal is marked

NC (normally closed), C (common) and NO (normally open).

The normally open and normally closed positions are with the

relay de-energized. The relays are energized when they are

tripped by the assigned level or alarm. The relays can be

assigned for different functions which are explained in the

Operation Section of this manual.

needed will depend on the amount of resistance of the

load connected to the 4-20 mA loop. To determine the

size of the DC power source, use the following equation:

DC volts = (Max load/50) + 8

Two test points are provided on the bottom of the back

housing to allow adjustment of the 4-20 mADC signal. A

load must be connected to the 4-20 mADC output

terminals for these test points to work. Refer to the

Operation Section when adjusting Zero and span.

FB-1 (FULL FACE)

SENSOR INSTALLATION

GENERAL DESCRIPTION

The Model 2100 FB-1 sensor has a PVC plastic

housing. The sensor is back filled with an epoxy resin.

The sensor head has a 3/4 inch NPTmounting nipple to

secure the sensor to the mounting bracket and attaching a

conduit fitting for routing the sensor cable back to the

elecontric enclosure. Metallic conduit must be used to

run the sensor cable back to the electronics. The sensor

must be mounted level. An ‘L’ mounting bracket is

supplied with the sensor.

The sensor is supplied with 50, 100, 300 or 500 feet of

continuous cable, or additional cable (up to 1000 feet

total) may be spliced onto the cable from the sensor. Only

Belden 9222 cable should be used.

A component change in the electronics may be required

if the sensor cable length is changed from that shipped by

the factory. The critical lengths of the cable for the

component change are 150 feet and 500 feet. The

following shows the component value for C11 according

to the sensor cable length (see Figure 2-7, page 2-11 for

location):

0 to 150 feet — C11 = 6800PF

151 to 500 feet — C11 = no component

501 to 1000 feet — C11 = 470 uH

INSTALLATION

The meter is normally programmed at the factory to a

specific application. The sensor must be installed to the

proper mounting dimensions to ensure the accuracy of the

flowmeter. Refer to the data sheet in the front of this

manual for these dimensions.

Mounting Hole

The dimension that is used when mounting the sensor is the

vertical calibrated (Vcal) mounting distance. This is the

distance from the surface of the fluid at no (zero) flow, to

the face (bottom) of the sensor. There are two regions that

make up the Vcal distance. These are the sensor offset

and the customer selected full scale headrise.

Level of fluid at no flow 6° Beam Angle

NOTE:

If sensor is exposed to sunlight, a sun shield should be used. Refer to System Diagram, Page 1-3.

The sensor offset is the distance from the maximum level

of the fluid to the face of the sensor. The minimum offset is

12 inches.

The full scale headrise is the level of the fluid at the

customer’s selected full scale flow for the flume or weir.

The minimum full scale headrise is 4 inches and the

maximum is 132 inches.

Therefore,

Sensor vertical mounting distance (Vcal) =

Customer full scale headrise + Sensor offset

When the Model 2100 is programmed at the factory, the

Vcal is determined by taking the full scale head rise of the

maximum capacity of the flume or weir plus 12 inches for

the offset. This is done so that the flowmeter can be rescaled

to a higher full scale flow in the future without having to

move the sensor. This is reflected on the Mounting and

Calibration Data Sheet in the front of the manual by the

Max. Capacity (Element) and Customer Maximum

Headrise. When the Customer Max. Flow is less that the

Max. Flow (Element) then the sensor offset will be 12

inches plus the difference between Max. Flow (Element)

and the Customer Max Headrise.

The other mounting dimension that is important is the

Horizontal (H) dimension. This is the horizontal distance

from a reference point on the flume or weir to the sensor.

Pages 2-6 through 2-9 show this dimension for the

commonly used flumes and weirs.

Another aspect that must be considered when mounting

the sensor is the distance of the sensor from the walls of the

structure in which the fluid is flowing. If the sensor is too

close to the wall, reflections may occur which could cause

inaccuracies in the level measurement. The beam angle of

the transmitted signal from the sensor face is a maximum of

6 degrees. To determine the distance the sensor must be

mounted from the wall, multiply the Vcal distance times

0.0524. This will give the distance required from the wall to

the sensor housing.

The exit hole for the sensor cable on the top of the

housing is a 3/4" NPT nipple which is used to mount the

sensor to the mounting bracket and connecting the conduit

for the cable. The cable must be run in metallic conduit to

prevent any stray noise interference from affecting the

meter’s operation.

The mounting bracket provided with the sensor can be

mounted directly to the wall for Vcal distances of 60 inches

or less. An extension, or mounting brace, to the mounting

bracket will be required for Vcal distances greater than 60

inches.

When installing the sensor, it is imperative that it be level.

A level should be placed on top of the sensor and

adjustments made to the mounting bracket to ensure the

sensor face is level to the fluid.

This completes the FB-1 sensor installation procedure.

Refer to the electronic wiring section for connecting the

sensor cable to the electronics.
