General Description

These Max transmitters are designed to work with the

Model 296

entire family of Max Flow Meters to provide extremely precise

ow measurement in a cost effective package. Different options

for electrical connections and temperature ranges cover a wide range of application environments – from the laboratory to harsh industrial processes.

Model 295

This latest generation of transmitters use modern sensor technology coupled with advanced signal processing to deliver new levels of performance and reliability. Hall sensors are used to

Ex Proof Model 295

detect the position of a driven magnet inside a Max Flow Meter. Changes in position are tracked by a microprocessor, which

generates an output proportional to the ow rate. Advanced signal processing provides both ne angular resolution (0.36 degrees rotation) and rapid response (output updated every one millisecond).

These transmitters are typically mated to a mechanical ow meter, congured, and calibrated at the factory as a matched set. This ensures accuracy and allows quick setup in the eld. For eld

installations where the transmitter has not been setup with a meter at the factory, an optional serial

interface kit provides full access to all conguration options and parameters.

Transmitter Features

High resolution measurement - Congured output ranges to any valve within ± 10 Vdc or ± 20 mA. Linearization of up to 16 points to fully describe the ow meter’s output curve and achieve the highest system linearity over the meter’s entire operating range.

Compensation Algorithm – Compensates for variations in Hall sensor and ow meter characteristics to provide a stable, undamped output that accurately represents the instantaneous ow rate. This

feature is factory set when the meter and transmitter are mated together. If the transmitter is changed, the compensation can be performed via a button on the PCA.

Anti-Dither Buffer - Masks the false output that may occur at very low ow rates in the presence of

vibration or hydraulic noise. If the meter reverses direction the output signal will be interrupted for

a user selected portion of a meter rotation. Reverse ow exceeding the buffer setting will result in an output proportional to reverse ow rate. The buffer quantity can be set from 1% to 100% of a

revolution.

Installation - Model 295, 296

Model 295, 296 — Mechanical Installation

1. The transmitter is attached to the ow meter’s threaded magnet shield. Hand tighten only. (~ 3 ft-lb)

2. The transmitter lid has four thread paths. To realign the cable, remove the lid and rotate up to 180°

and retighten using an alternate starting point. Tighten to compress the O-ring seal.

Removal

1. Remove electrical connections

2. Unscrew transmitter, using a wrench if necessary.

Removal note: The transmitter does not need to be removed from the ow meter for any eld servicing or adjustments. Normally, the ow meter and transmitter are shipped back to the factory for calibration or service as a unit. If the transmitter needs to be removed from the ow meter for installation, be sure to retighten the transmitter snugly in order

to ensure proper sensor alignment.

Moisture Protection

On all models, the housing is designed as a liquid and vapor-tight enclosure. There are O—ring seals at the lid and possibly also the base of the housing — these need to be fully seated. A properly sealed transmitter will prevent the formation of damaging moisture inside the housing.

Turck connector Model: The connector is sealed to the lid at the factory and is ready for use. NPT Model: To ensure a moisture-tight seal, apply appropriate sealant to the threads at installation.

Electrical Installation —

Wiring

The electrical connector versions are pre-wired inside the transmitter and ready to accept a mating

Rotation/Output Indicators

All of the microprocessor based transmitters incorporate a LED to indicate that they are detecting magnet rotation in the meter.

An alternating red/green or blue/green LED indicates that the circuit is detecting a rotating

magnet and should provide an output. Additional LED’s are present for setup, programming and

troubleshooting and are not intended for general use.

Note: There are no selections or adjustments to be made on the circuit board. The only method of altering the setup parameters is through the serial interface program. Contact the factory regarding

P/N 294-100-050, user interface software.

Field Compensation of transmitter

When a new transmitter is attached to a ow meter, the compensation routine should be performed to optimize the performance of the system. This routine requires a steady ow rate which turns

the meter at between 15 and 1000 RPM. If you are using the interface software, please consult the “software Interface” manual for instructions. For the Model 295 and 296, the sequence is as follows:

1. Stabilize the ow rate

2. Push the compensation button on the PCA

3. The blue/green LED will change to solid blue for 6 to 8 revolutions of the meter

4. A green indicator light indicates a successful update of the compensation, a red indicator light indicates that the previous compensation has been retained.

High Temperature Operation Above 65°C (150°F)

The operating limit of the meter/transmitter is a function of both the ambient and the metered uid

temperature, as shown in the following graphs. Although the electronic components are rated to

80°C (175°F), additional heat can be conducted from the ow meter into the transmitter housing requiring a lower ambient temperature limit for high uid temperatures.

To prolong the life of the transmitter and reduce the risk of component related failures over time,

high ambient temperatures >65°C (150°F) should be avoided if possible. It is a good idea to locate

the transmitter away from hot spots such as steam pipes, ovens and heaters. When working with

elevated uid temperatures >65°C (150°F), insulating the ow meter is recommended to reduce the

risk of burns, and to reduce the heating of the electronics by convection of hot air off of the meter

(especially for larger meters). The upper temperature limits shown in the curves rely on ambient

convection to remove heat from the transmitter housing, cooling the electronics. For this reason, if operating near the upper temperature limit, the transmitter should not be insulated. At these elevated temperatures, the transmitter will be very hot — exercise appropriate caution.

Mechanical Installation

The outer housing freely rotates to align the conduit hole with your electrical connection point. If the transmitter is already attached to the meter skip to step 5:

1. To attach the transmitter to the ow meter, apply a small amount of low strength thread adhesive,

such as Loctite™, on the threads and screw the transmitter into the threaded recess on top of the

ow meter.

2. Locate the locking set screw below the conduit hole and remove it. Rotate the outer housing clockwise until the screw hole lines up with a hole in the inner housing. Inserting an Allen key into the

threaded hole while rotating the housing can help in nding the point of alignment. Now re-insert the

set screw and hand-tighten it to lock the inner and outer housing together.

3. Finish tightening the transmitter onto the meter by applying a torque of 2 to 5 ft.-lb. (2.7 to 6.78 N-m).

4. Now back out the locking screw until it is ush with the surface of the transmitter.

5. The housing can now be rotated to align the conduit port in the desired direction.

6. To open the housing for wiring, remove the locking screw at the edge of the lid and then remove the cap using a 3/8” socket drive.

7. Install conduit. Within 18” of the housing install a conduit stop and fully seal with potting compound.

8. Connect wires to terminal block as shown below.

9. A case ground terminal is provided internally, but if grounded metallic conduit is not used, then

one of the external grounds below the conduit tting must be used. For metric- use either a 6 or 8

mm long stainless steel M5 x 8.0 bolt. steel #10-32 bolt.

For inch measurement – use either a 1/4” or 5/16” long stainless

10. Reattach cap and tighten to 40in-lbs to seal enclosure. Install safety lock screw at the edge of the lid and hand tighten.

Page 10

Removal from Flow Meter

Note: the transmitter does not need to be removed from the ow meter for any eld servicing or adjustments. Normally, the ow meter and transmitter are shipped back to the factory for

calibration as a unit.

1. Remove the locking screw at the edge of the lid and then remove the cap using a 3/8” socket drive.

2. Disconnect wires at the terminal block and remove wiring conduit from transmitter.

3. Locate the locking set screw below the conduit hole and remove it. Rotate the outer housing clockwise until the screw hole lines up with a hole in the inner housing. Inserting an Allen key into

the threaded hole while rotating the housing can help in nding the point of alignment. Now re-

insert the set screw and hand-tighten it. This will lock the inner and outer housing together.

4. Unscrew the transmitter, using a strap wrench if necessary.

Moisture Protection

The housing is a liquid and vapor-tight enclosure certied to IP66. There is an O-ring seal at the

lid of the housing — the seal needs to be fully seated to provide moisture protection and achieve

ameproof specications.

About Explosion proof installations

For the Model 295 and 296 to fully adhere to the HazLoc certications, the wiring must meet the

appropriate codes.

(Use of a wire conduit does not make the installation explosion proof – read below.)

The transmitters which are certied for use in hazardous locations require the use of a 1/2” NPT conduit tting. The wiring conduit must be sealed with a conduit stop within 18” of the device. If you choose to use exposed cables, cable seals must be used with sealing ttings and the wiring must be an approved armored cable. (For detailed information on the joint constructions used to achieve a ame proof housing, please contact Max Machinery.)

Electrical Installation

Use wiring that is between 20 and 28 gauge and rated to at least 5°C above the maximum ambient temperature, and rated to at least 80% of the maximum uid temperature.
