The OSS-B1 universal current meter is a field-proven instrument for measuring the velocity of water in open and closed
channels. It is used for point measurements of flow velocities on the water surface or in vertical profiles down to the
riverbed at flow speeds of 0.025 m/s to 10 m/s.
One of the great features of the OSS-B1 is it can be used with 20 mm diameter wading rod and relocating device,
streamlined suspension tube, portable winches and permanent cableway installations, with streamlined or ground feeling
weights. A tail fin assembly is provided to control directional stability during suspended measurements.
The OSS-B1 comes with lots of accessories which enable the user to endure water flow measurement easily and
accurately.
All current meters manufactured by Hyquest Solutions are calibrated in our purpose built high velocity rating tank prior
to shipment. This rating tank is considered as best in the world since it can run at a velocity of 0.005 m/s minimum and 8
m/s maximum with a velocity resolution of +/- 0.001 mm
As part of our service we are able to recondition and recalibrate current meters of any make, including electromagnetic
and other solid state meters. Calibration is directly traceable to International Standards.
All current meters are calibrated in accordance with AS 3778.6.3-1992. This standard is identical with and has been
reproduced from ISO 3455:1976.
The purpose of this manual is to make the user familiar with the OSS-B1 current meter. It is a sensitive and reliable
precision instrument. It is advisable to read this manual carefully and fully understand its use. After reading this manual if
you are not sure about any details, please do not hesitate to contact our office (contact details are on the cover of this

Operation
3Operation
One impulse signal is produced per Fan revolution. As shown in figure1 below, this signal is generated by an encapsulated
reed switch (1) which resides inside the meter body (2) and a permanent magnet (3) set into the rotating Fan assembly. A
cover sealed with two O-rings provides a water-tight housing for the reed switch, while gold plated contact pins ensure
low-resistance signal passage.
The voltage must not exceed 9V DC. Provided the impulse counters have spark-suppression circuits, the meter can be
loaded with up to 1.6 watts. All our counters meet these requirements (refer to specification).
Four type of stainless steel Fans (4) can be used with this meter, all these Fans are supported on bearings which run within
the oil filled hub of the Fan assembly. The capillary oil passage between the stainless steel axle (5) and Fan carrier (6),
prevents entry of water to the bearings. A locknut on the shaft locates the bearings and sets the end float of the assembly.

Maintenance
4Maintenance
The maintenance of the OSS-B1 current meter can be divided in three sections as stated below.
Section 1: Prior to discharge measurements
Initial set up
§ Open the case and pick up the Fan assembly.
§ Undo the fan carrier.
§ Remove fan carrier and shaft assembly (do not put it down anywhere it may attract dirt particles).
§ Hold the fan upright and ¾ fill with oil.
§ Replace the oil bottle cap.
§ Replace axle and fan carrier, excess oil will be forced up through the capillary gap around the axle, ensure fan carrier
is tightened.
§ Wipe the excess oil of the meter using lint free paper towel.
§ Do not forget to close the oil bottle straight after usage to avoid contamination of the oil.
§ Slide the fan assembly into the body and use the stubby screwdriver to tighten the retaining screw to lock the fan
assembly in place.
§ Prior to spin test hold the current meter in the horizontal position and spin by hand for approx. one minute to get
rid of the hydraulic pressure.
§ Spin test the meter against time. This is required to test the performance of the shaft and bearings.
§ Spin test results are dependent on the fan type and temperature (see table below).

§ After the spin test is performed connect your current meter to the counter using the lead, this important to test the
lead, reed switch and counter.
Section 2: During and after Discharge Measurements
After every discharge measurement, or one hour of use the current meter should be cleaned and refilled with oil, if
continuing a discharge measurement.
§ Spin test meter.
§ Undo the cleaning jar cap and ¾ filling with white spirit.
§ Remove fan assembly from meter body by undoing the retraining screw and separating the body from the fan.
§ Remove fan carrier and shaft assembly (do not put it down anywhere it may attract dirt particles).
§ Empty the old oil in a recycling container (do not tip oil on the ground this will pollute the environment).
§ Put the shaft and bearing assembly into the cleaning jar.
§ Agitate them.
§ Fill up the fan with white spirit put your thumb in place of carrier and shake it really hard for a few seconds.
§ Blow dry the shaft assembly, fan carrier and fan.
§ Re-assemble the fan, if discharge measurement is finished.
§ Wipe box clean and return the fan assembly to the case.
§ If continuing a discharge measurement, Refill the fan with oil as per section 1.
§ Spin test the current meter at per section 1.
§ Repeat all the above steps for every discharge measurement.
§ Tip the white spirit in a spare bottle.
Note: Both oil and white spirit can be recycled using filter papers.

Maintenance
Section 3: Tips for Easy Maintenance
It is advisable that the user maintain the OSS-B1 current meter at all time.
§ Keep the OSS-B1 case clean.
§ Clean all the tools after usage.
§ Use lint free paper towels and white spirit (do not use methylated).
§ Office service is required for the OSS-B1 current meter about once a month if it is used on a daily basis (i.e. Fully
dismantle shaft assembly, fan carrier and fan; Clean each item using hot soapy water and then rinse with white spirit).
§ Check the lead and new the ends connections.
§ If the current meter fails the spin test refer to the mechanical fault finding section for details.
§ Test lead, counter and reed switch (see electrical fault finding section for details).
For more information, see the following subsection:
§ Service and Recalibration
4.1 Service and Recalibration
§ Recalibrate the current meter every 300 hours of use or once a year whichever comes first (see Hyquest Solutions
calibration certificate for details).
§ For recalibration only, send the body and the fans that require calibration (to save weight). However, if other items
needs repair they can be sent with the body and fans.
Note: Hyquest Solutions provides a recalibration and repair service for most types of current meters.

Mechanical Fault Finding
Symptom
Possible Causes
Action
Remark
Failed spin test
§ Dirty or faulty
bearings.
§ Clean Bearings and try to spin
test again. If Problem persists
replace bearings.
§ Dirty bearings can be
identified towards the end of
the spin test when the fan
stops suddenly.
§ Bent shaft.
§ If the shaft is slightly bent
return to HS for repair.
§ If the shaft is very bent return
to HS for replacement.
§ Bent shaft can be identified by
looking at the pointed centre
of the fan during spin test. If
this point is turning off-centre
this indicates that the shaft is
bent.
Electrical Fault Finding
If an electrical fault has been traced to the current meter, the following conditions should be checked using a multi-meters
or impulse counter.
Faults will be either CLOSED CIRCUIT or OPEN CIRCUIT, and if the CMC-20A counter is used, set the control switches to
“ON” and “INT” (ie. no time limit). Spin the Fan and if the audible signal sounds continuously, the fault is a “CLOSED
CIRCUIT”. If no audible signal is heard, the fault then is an “OPEN CIRCUIT”.
Closed Circuit Fault
Symptom
Possible Cause
Action
Fault occurs only when meter in
water.
§ Water entering contact plug
receptacle and earth between plug
and body
§ Replace damaged plug or missing
seal (see figure 7)
