ENCLOSURE DESCRIPTION

The Model 2100R+ ultrasonic flow meter with circular

chart recorder is housed in either a NEMA 12 or NEMA 4X

enclosure.

The NEMA 12 enclosure is suitable for indoor use and

is designed to be panel mounted. It can be supplied with

heater and thermostat for indoor installations in buildings

that are not heated in the winter. Mounting hardware is

provided for panel mounting of the enclosure. Care

should be taken when selecting the mounting location so

that the recorder door can be opened completely for

access when changing charts.

INDOOR ENCLOSURE DIMENSIONS

The NEMA 4X enclosure is suitable for outdoor use

and can be wall or pole mounted. It comes equipped with

heater and thermostat. The door can be supplied with or

without a window. The door is provided with two

lockable latches. Caution should be used when mounting

the enclosure so that it is not exposed to direct sunlight. A

sun shield is recommended to prevent the temperature

inside the enclosure from reaching above the maximum

rating of the electronics (see temperature specification

under General Specifications). Viewing window is

optional.

WIRING CONNECTIONS

The indoor case has six 7/8" diameter knockouts for

use of 3/4" conduit connections. Three are located on the

bottom of the case and three on the back of the case. The

three you use will depend on whether you panel or wall

mount the enclosure. The outdoor enclosure has three

7/8" diameter knockouts located at the bottom of the case.

Local regulations for proper grounding and connection

of the power to the recorder should be strictly followed.

The power wires are connected to the terminals located

on the inside back of the enclosure (see Figure 2-1). To

gain access, open the enclosure door and loosen the two

screws at the top and bottom left side of the chart plate

and swing out the chart plate. The AC voltage for which

the unit has been set up for will be clearly marked near

the terminal strip. Verify that you are connecting the proper

voltage to the recorder. The terminal labeled H is the High

(black) wire, the terminal labeled N is the Neutral (white)

wire and the terminal labeled G is the Ground (green)

wire. The power wires from the terminal strip to the

recorder circuit board and the flowmeter power board are

prewired from the factory.

The terminal blocks on the recorder circuit board have

snap-on connectors. To connect the output wires for the

relays or 4-20 mA retransmission, pull off the connectors

from the terminal strips. Route the signal wires through

the wiring clips. Loosen the screws on the connectors.

Strip off about 1/4 inch of insulation from the wires.

Insert the wire into the proper connector and tighten the

screw securely. After connecting all of the wires to the

connector, snap the connector back on the terminal strip.

different functions. See the Recorder Operating Section

of this manual.

RECORDER 4-20 mADC OUTPUT

The 4-20 mADC output is a retransmitted output of the

flow signal which can be connected to other external

devices. The wiring connections must be connected in

series with the load, as shown above.

RELAY OUTPUTS - TB2 also is the terminal block

for the connections for the relay outputs. Terminal

connections 7 through 18 are used for the four relays

which are marked SW1, SW2, SW3 and SW4. These

relays are single pole double throw with a 1.0 amp 24

VDC or 0.5 amp 120 VAC current rating.

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 Model

2100 Operation Section of this manual on Page 3-13.

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 NPT mounting nipple to

secure the sensor to the mounting bracket and attaching a

conduit fitting for routing the sensor cable back to the

electronic 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 100 feet of triaxial cable.

The sensor can be ordered with 300 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 is required

depending on the length of the cable. This is done at the

factory based on the amount of cable ordered with the meter.

The critical lengths of cable for the component change are

150 feet and 750 feet. If the user increases or decreases the

length of cable, and the length change steps above or below

the critical length points, the factory should be contacted for

information regarding the correct component change.

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

flow meter. 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.

Dimension

6° Beam Angle

NOTE:

If sensor is exposed to sunlight, a sun shield should be used

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 headrise of

the maximum capacity of the flume or weir plus 12 inches

for the offset. This is done so that the flow meter 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 than 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

2-5

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 fluid.

This completes the FB-1 sensor installation procedure.

Refer to the Electronic Wiring Section for connecting the

sensor cable to the electronics.
