Introduction

Section 1: Introduction
1.1 System Description
The Model 375 is specically designed for slurry and highly viscous
applications where clogging of the sensor area is common. The Model 375
uses a 3.5” ush diaphragm to prevent unwanted clogging of the sensing area.
This submersible level device is made of 316 SS which offers outstanding
environmental protection and is available in depths up to 138 feet of water.
The non-fouling ush diaphragm is designed to eliminate unwanted buildup
of debris, fats, oils, greases, and other bio-solids by removing any potential
gaps on the measurement area. The high integrity seal’s heavy construction
eliminates the effects of turbulence on the sensor.
The 375 Series Transmitters indicate the level of liquid by continuously
measuring hydrostatic pressure via its sensing element, an ion implanted
silicon semiconductor chip with integral Wheatstone Bridge circuit. Once
the sensor measures the pressure, the data is transmitted by a 4 to 20 mA
output signal. This design provides for excellent reliability in remote and
inaccessible locations.
The Model 375 is approved for intrinsically safe operation in hazardous
locations as designated by Class I, Div 1, Groups A, B, C & D and Class II,
Groups E, F & G. when used with an approved barrier.
All Model 375 transmitters are equipped with a sealed cable termination
area and moisture absorbing desiccant. The purpose is to restrict moisture
from entering the transmitter through the cable vent.
Features
• Oversized 3.5” ush diaphragm to prevent clogging
• 0.25% Full Scale Accuracy
• Intrinsically Safe for Class 1 Division 1 Applications
• Custom Pressure Ranges and Cable Lengths
• Extremely rugged 316L SS construction
• Two-wire, 4-20 mA standard output
• Reverse polarity and surge protection
Applications
• Lift Stations
• Sewage Levels
• Slurries
• Storm Runoffs
• Pump Control

Section 2: Installation
To install the Model 375 Transmitter, connect the surface end of the cable to
the Ametek Model CDM Meter Controller or other power source and indicator.
Suspend the transmitter into a well or tank supported only by its attached
shielded electronic cable. Insure that the opening in the well or tank cover
is large enough for possible future removal of the transmitter.
2.1 Safety Information
The overall system is designed to prevent accidental shock to the operator when
properly used. No design, however, can insure the safety of an instrument
improperly installed or used negligently. Read this manual carefully and
completely before operating the instrument. Failure to read this manual in
its entirety could result in damage to the instrument or injury to the operator.
To avoid possible shock hazard install in a grounded enclosure, prevent live
parts being touched and ground the sensor sheath and housing. Follow
wiring diagrams and local regulations. Installations where failure of this
equipment may cause personal injury, property loss, equipment damage or
nancial loss, backup failsafe protection must be used.
2.2 Unpacking & Inspection
Carefully remove the contents of the shipping carton and check each item
against the packing list before destroying any packing material. If there is
any shortage or damage, report it to the factory immediately.
When this transmitter is used with the AMETEK Drexelbrook CDM Controller,
the transmitter Model Number is identied on the nameplate of the CDM in
the section labeled “USED WITH.” This is because the CDM is calibrated
with, and should be used only with a specic Submersible Transmitter. Look
for a correlation between the two instruments.
2.3 Operational Checkout
Before installing the 375 Series Transmitter, make sure the system is
operating by doing a bench check.
WARNING:
Do not connect any wires while Power is applied.
For temporary connections, refer to diagrams in Wiring Section 2.5 of this
manual. Connect AC power to the controller and/or with which it is to be
used. Apply power and allow a ve-minute warm-up.
With no pressure applied to the transmitter, the meter should display zero
(or for “drawdown” the reading corresponding to the depth below ground
level that the transmitter will be when installed.)

2.4.2 Placement
Caution: The Model 375 Transmitter must be supported by a stainless
steel relief cable that is attached to the tabs on the transmitter. The relief
cable can be customer supplied. Figure 2-2 shows common installation
recommendations. Ametek provides this relief cable as an option. Reference
model number K554164 when ordering. Supporting the transmitter only by
its attached electrical cable voids the warranty.
Caution: Do not allow transmitter to remain in liquid when it freezes solid.
This will apply mechanical force to the sending diaphragm of the transmitter.
Excessive force will result in transmitter damage or destruction.
2.3 Operational Checkout (continued)
CAUTION: Do not simulate an increase in pressure by applying mechanical
force to the sensing diaphragm of the transmitter. Excessive force will result
in damage to or destruction of the transmitter.
When pressure is applied to the transmitter, the display should increase,
and then return to the original reading when pressure is removed. The
Transmitter can be pressurized by lowering it into water or by applying air
pressure from a calibration device.

2.4.3 Model 375 Series Transmitter
CAUTION: The cable grommet is specially installed by factory-trained
personnel to assure that it remains watertight. Any adjustment or removal of
the grommet may destroy the watertight feature thus exposing the transmitter
to water seepage, causing an electrical short and transmitter failure. Any
adjustment or removal of the cable grommet voids the warranty.
CAUTION: The diaphragm seal assembly is installed by factory trained
personnel and should not be modied in the eld. Any adjustment or removal
of the diaphragm seal assembly voids the warranty.
CAUTION: The waterproof cable should not be kinked or nicked, which
will allow water to seep into the cable and short out the transmitter.
Figure 2-2
Transmitter Installation Considerations
2.4.4 Provide Signal Noise Isolation
The transmitter should not be mounted close to high current switching relays
or in an enclosure containing such relays. Low voltage wiring (transmitter
signal wires and analog output wires) should be separated from high voltage
wiring (115, 230 & 440 Vac) and should be shielded.

2.5 Wiring
WARNING:
Do not connect any wires while AC Power input is applied.
2.5.1 Surge Protection
Surge protectors are available as an option item (see Parts & Accessories
in Section 3 of this manual). It is strongly recommended to protect from
secondary surges and lightning on outdoor installations. Install in accordance
with the applicable drawing that is supplied with the surge protector and
the following instructions:
1. Lightning protection devices should be placed as close to the meter or
transmitter as possible and wired in accordance with Local Electrical
Codes in an approved watertight enclosure.
2. If the distance between the meter and transmitter, or meter and recorder
is less than 100 ft., only one protector per line is needed.
3. Use No. 8 AWG ground wire or better from protector.
4. Keep ground wire less than one foot long and tie to a suitable ground rod
or metal frame ground. Surge capability is only as good as the grounding
method. All ground connections must be installed.
5. Install protectors in weather-tight enclosures.
6. Run signal lines shielded and away from power lines.
7. Mount the fused switch panel as close to the meter as possible. Wire
according to the Local Electrical Code.
8. Lead lines for 110 Vac and 220 Vdc protectors should be cut as short as
practical.
