Pulse tester1.

Introduction1.1

PULSE TESTER, type no. 66-99-279, is espe-

cially designed for use during the verifica-

tion process. The tester has the following

functions:

Galvanically separated pulse outputs•

Integral supply for ULTRAFLOW• ®

LC-Display with counter•

An externally managed “Hold” function•

Can be fitted directly onto MULTICAL• ®

base (Type 66-)

Pulse inputs (M1/M2)

Counter inputs Max. frequency: 128 Hz

Active signa Amplitude: 2.5 - 5 Vpp

Pulse duration >1 msec.

NB: There are one or two pulse inputs/

outputs depending on the base unit.

Flow meter with transistor output1.

The transmitter is typically an opto

coupler with FET or transistor output.

This is connected to terminals 10 and

11 for water meter M1 or terminals 69

and 11 for water meter M2. The transi-

stors leak current must not exceed 1 µA

when switched OFF. UCE when switched

ON must not exceed. 0.5 VDC.

Flow meter with relay or reed switch2.

output

The transmitter is a reed switch,

typically on a vane wheel or Woltmann

meters, or relay output from MID-meter

or similar. This type of transmitter

should not be used, as the quick pulse

input may give rise to problems due to

bouncing.

Flow meter with active pulse output,3.

supplied by the pulse tester

This connection can be used with

either KAMSTRUP’s ULTRAFLOW®or

KAMSTRUP’s electronic pick-up for vane

wheel meters.

Flow meter with active output and own4.

supply

Flow meters with active signal output

should be connected as shown in fig. 1,

pt 4. The signal level must be between

3.5 and 5 V. Larger signal levels can be

connected via a passive voltage divider,

e.g. on 47 kΩ/10 kΩat 24 V signal

level.

Hold function1.3

When the Hold-input is activated (input ad-

ded to high level), counting on the counted

pulses will stop.

When the Hold-signal is deactivated (input

added to low level), counting is restarted.

Counters can be reset by pressing the key

on the right hand side.

Key functions1.4

The left-hand key is used to

change between display/

counter for the two flow

meter inputs. The display

indicates with M1 or M2

which flow meter inputs/ counters are

currently displayed.

The right-hand key is used to

reset the two counters (M1

and M2).

Amplitude 1.5 - 30 VDC

Using the pulse tester1.5

The pulse tester can be used asfollows:

Standing Start/Stop of the flow meter•

using the integral pulse counters.

Standing Start/Stop of flow meters using•

pulse outputs to external test equipment.

Flying Start/Stop of flow meters using•

integral counters, controlled by external

equipment (Hold).

Changing the battery1.7

If the pulse tester is used continuously, we

would recommend that you replace the bat-

tery once a year.

The battery should be connected to the

terminals marked “batt.”. The red wire to +

and the black wire to -.

Power consumption:

Consumption with no meter

connected 400 µA

Max. power consumption with two

ULTRAFLOW®connected 1.5 mA

NB: The supply to the pulse tester must

be disconnected, if the connection bracket

is equipped with a battery or externally

supplied.

Verifying ULTRAFLOW2. ®

Installation2.1

ULTRAFLOW®with flow range from 0.6 m³/h

to 2.5 m³/h (DN15 and DN20) can be fitted

without considering the inlet pipes.

All other ULTRAFLOW®sizes must be fitted

so that the inlet pipe is straight at min. 3...5

x DN.

Please consider the installation angle when

fitting ULTRAFLOW®. Please refer to the

restrictions stipulated in the installation

manual for ULTRAFLOW®

attained and when commencing verifica-

tion, takes 16 seconds.

MEASURING FLOW•

To attain a correct flow measurement, ver-

ficiation should take at least 3 minutes.

Test parametres are set up in accordance

with German regulations relating to accur-

acy class C.

The individual test time is selected on the

basis of:

Min test time of 3 min (Qn)

Water quanitity of at least 10% of water

quantity pr hour (Qtand Qmin)

Water quantity for Qt- corresponding to

min. 1000 pulses

Water quanity for Qmin corresponding to

min 500 pulses

These suggestions can be optimised for

each individual bench and, of course, with

consideration for the test objectives.
