2 About this product

The flow meter DulcoFlow

®

is intended for use

in measuring pulsing volume flows in the range

from 0.1 to 80 l/h. All parts coming into contact

with flow media are made from PVDF. This

ensures that aggressive media can also be

measured without problem. The device is

installed approximately 30 cm after the pump in

the metering line. Interfering influences, such

as air bubbles, are identified and forwarded to

the analysis unit as an error message. With the

delta, it can only be used with the fast metering

stroke version.

The DulcoFlow

®

flow meter can not only be

used for recording and measurement of volume

flows, but also for monitoring individual

metering strokes. In this case the pump is cali‐

brated to the lifting volume set at the pump. A

lower and upper limit can be entered, which if

exceeded or undershot, results in no feedback

to the pump. This creates an error message.

The connection to the pump takes place via the

input for the "Flow Control" dosing monitor

The device is designed for wall mounting.

Safety information

WARNING!

Danger of electric shock

A mains voltage may exist inside the

housing.

– If the housing has been damaged,

you must disconnect the device from

the mains immediately. It may only be

returned to service after an authorised

repair.

WARNING!

Warning of dangerous or unknown feed

chemical

Should a dangerous or unknown feed

chemical be used: It may escape from the

hydraulic components during maintenance

work.

– Take appropriate protective measures

before working on the device (safety

glasses, safety gloves, ...). Observe

the safety data sheet for the feed

chemical.

–

Drain and flush the hydraulic parts

before working on the device.

CAUTION!

Warning of feed chemical spraying around

Feed chemical can spray out of the

hydraulic components if they are manipu‐

lated or opened due to pressure in the

hydraulic and adjacent parts of the system.

– Disconnect the pump of the device

hydraulic system from the mains

power supply and ensure that it

cannot be switched on again by unau‐

thorised persons.

– Depressurise the system before com‐

mencing any work on hydraulic parts.

CAUTION!

Danger of personnel injury and material

damage

The use of untested third party parts can

result in personnel injuries and material

damage.

– Only fit parts to the device, which

have been tested and recommended

by ProMinent.

NOTICE!

Warning of illegal operation

Observe the regulations that apply where

the device is installed.

Information in the event of an emergency

In an emergency, disconnect the device from

the mains!

If feed chemical escapes, also depressurise the

device hydraulic system. Adhere to the safety

data sheet for the feed chemical.

parts - refer to the chapter "Decommis‐

sioning"!

Only send the unit complete with a filled in

Decontamination Declaration form. The

an integral part of an inspection / repair

order. A unit can only be inspected or

repaired when a Decontamination Declara‐

tion Form is submitted that has been com‐

pleted correctly and in full by an authorised

and qualified person on behalf of the oper‐

ator.

The "Decontamination Declaration Form"

can be found in the Appendix or under

www.prominent.com

.

NOTICE!

preferably in its original packaging.

– The packaged unit should also only

be stored or transported in accord‐

ance with the stipulated storage con‐

ditions.

– The packaged unit should be pro‐

tected from moisture and the ingress

6 Functional description

The DulcoFlow

®

flow meter measures the

volume flow of pulsing flows. The ultrasonic,

time of flight measurement method is used. For

the time of flight measurement, a sound signal

is alternately transmitted in and against the

direction of flow. The time difference is then a

measure of the mean flow velocity. Use of the

ultrasound measurement method automatically

compensates any temperature induced

changes in the medium. Operation without

moving parts guarantees a long service life and

wear-free operation.

The DulcoFlow

®

calculates the mass flow from

the volume flow and the density of the feed

chemical.

Additionally the DulcoFlow

®

can measure the

pressure surges of the metering pump and

hence replace a dosing monitor such as the

Flow Control. A metering pump such as the

gamma/ L or delta

®

can use these signals as

acknowledge pulses for its individual strokes. If

the acknowledge pulses are missing or if the

capacity exceeds the specified limit values, the

metering pump stops after an adjustable

number of missing pulses and goes into fault

mode - see metering pump operating instruc‐

tions.

The DulcoFlow

®

gives the flow reading, stroke

feedback, or error messages via the various

output types.

7 Assembly and installation

Safety information

WARNING!

Carry out the assembly work before the

electrical installation is undertaken.

WARNING!

Observe the information in the "Technical

data" chapter.

WARNING!

Danger of an electric shock

If the device is used outdoors without a

cover or weatherproof roof, water may be

able to collect on the seals and penetrate

the housing or direct sunlight may cause

the housing to be corroded.

– Always use a cover or weatherproof

roof when using the unit outdoors.

CAUTION!

Warning of illegal operation

Observe the regulations that apply where

the unit is to be installed.

The device is resistant to normal atmos‐

pheres in plant rooms.

7.1 Installation

Install the device so that the hose between

it and the pump is approximately 30 cm

long.

This ensures it measures accurately.

Mount the device vertically.

This ensures it measures accurately.

Mount the device vertically on the wall

using both eyes on the housing.

Do not forget the washers.

7.2 Hydraulic Installation

CAUTION!

Warning of escaping feed chemical

Feed chemicals can escape in the event

that the hose lines are incorrectly installed.

– Only use original hoses with the

specified hose dimensions.

– Avoid reducing the hose sizes.

Assembly and installation

15

Flow direction

The flow direction through the device goes

from the bottom to the top.

Injection valves, back pressure

valves, relief valves

Injection valves, back pressure valves or

relief valves must not have any effect on

the measurement.

Relief valves

It is best to install a relief valve before the

flow meter, so that the displayed flow or

flow volume actually corresponds to the

value which is being metered into the

system if the relief valve triggers.

Hydraulic Dampers

Hydraulic dampers, like accumulators,

inline dampers or bladder accumulators /

diaphragm accumulators must not have

any effect on the measurement.

A zero flow must be available.

The damping must not push the flow mean

value beneath the measurement threshold.

Installing the hosing:

1. Cut off the ends of the hoses (6) so that

they are straight.

2. Unscrew the union nut (5) and push

over the hose together with the clamp

ring (4).

3. Push the hose end (6) up to the stop

over the nozzle (3).

4. Tighten the union nut (5).

5. Pull on the hose (6) and tighten up the

union nut (5).

7.3 Electrical Installation

WARNING!

Danger of electric shock

The use of a residual current circuit

breaker drastically increases survival

chances should persons come into contact

with the mains voltage due to an electrical

accident.

– Always fit a residual current circuit

breaker on-site.

A metering pump, PLC or other devices can be

connected to the flow meter.

The following alternative electrical outputs are

available via cable:

n Current output (identity code characteristic

"signal output "1"):

n Counter output (identity code characteristic

"signal output "2"):

Current output

The following can be signalled via the current output (standard signal output (mA)):

n Instantaneous flow

n Fault

Technical data:

Data Value Unit

Current* 0/4 .. 20 mA

Maximum load 400 Ω

* zero volt connection

Counter output as stroke feedback output

The counter output as stroke feedback output

can be used to signal stroke feedback, pro‐

vided it is set accordingly - see chapter "Set‐

tings".

1. To report stroke feedback at the

metering pump such as gamma/ L and

delta

®

, plug the cable from the flow

meter to the pump in the "dosing mon‐

itor" terminal.

ð

The identifier for the dosing monitor

must appear on the LCD screen of

the pump.

2. If it does not appear, make the neces‐

sary settings at the metering pump.

Assembly and installation

18

Counter output as frequency output

The counter output as frequency output can be used to signal flow or an error, provided it is set

accordingly - see chapter "Settings".

1. Remove the connected socket.

2. Remove the insulation of the leads to match the terminals of the other device.

3. Crimp on a suitable cable end sleeve.

ð

In this format, the cable can be connected to another device.
