USER MANUAL FTLG 807 (0112)
1 Introduction
IMO resolution A.212 (VII) and resolution A.328 (IX) give the following definition for a "closed
type" liquid level gauge:
“Closed devices, which penetrate the cargo tank, but which form part of a closed system
and keep the cargo (-tank contents) from being released, such as float type systems."
The HSH FTLG 807 series marine level gauge is a float type level gauge with a linear springmotor to provide power for measuring liquid level in cargo tanks.
The FTLG 807 series marine level gauge can be used on all types of ships carrying liquefied
gases in bulk.
The HSH marine level gauging system provides standard local digital level read-out, manual
float hoisting and locking, automatic float descent control and further possibilities for
centralized cargo handling with intrinsically safe level transmission and electronic digital readout, integral level alarms and a variety of electronic signal outputs.

1.1
Level gauge construction and working principle
The gauge head of the 807 series level gauge is made of two completely separated and closed
compartments. The communication between both compartments is indirect by means of a
magnetic coupling. One of the compartments, the so-called measuring drum compartment,
communicates directly with the tank, and is thus part of the closed system.
The measuring drum compartment houses an accurately machined measuring drum on which
a flexible multi-stranded measuring cable is wound in a fine, screw-thread like groove. The
float is fitted to the measuring cable and serves as level sensing element.
The measuring drum is coupled through a magnetic coupling to the spring-motor, housed in
the second compartment, the so-called spring-motor compartment. The spring-motor provides
a constant torque via the magnetic coupling to the measuring drum in the rotation direction
for winding-up the measuring cable. Under influence of the float weight a counter directed
torque is applied from the measuring drum to the spring-motor via the magnetic coupling.
The torque of the spring-motor is lower than the torque caused by float weight and measuring
wire. The difference in torque allows the float to descent, but with the float at the cargo
equilibrium will be reached as the float apparently obtains a lower weight in cargo. In this
situation the spring-motor maintains a constant pull in the measuring cable. When the cargo
level raises or lowers the float follows the level changes and causes the measuring drum to
wind-up cable or to release cable. The rotation of the measuring drum and spring-motor is a
measure for the amount of level change. To indicate the measured levels, a digital counter
mechanism is fitted at the spring-motor to "translate" the measuring drum rotation in mm's
level.
The spring-motor basically consists of a storage drum, a torque output drum and a length of
flat spring material.
Each position of the flat spring material is preset to the same curvature in such a way that it
can be completely straightened without deformation. Because of this presetting the spring
material curls up and forms a coil.
By mounting the coil on a free rotating storage drum and by uncoiling it reverse-bent on a
torque output drum, a constant torque drive is constructed as the tendency of the spring
material is to recoil to its preset curvature, thus imparting a constant torque to the shaft of the
torque output drum.
The 807 series marine level gauges are accurate level read-out instruments which are used
during loading or discharging of tanks. During the voyage the floats must be hoisted to
uppermost position. If, after loading, the cargo loading lines are blown empty, the floats must
be hoisted first. Failure to do so may cause considerable damage to the instruments.
The level gauge is provided with a float hoisting mechanism with magnetic slip-clutch that
prevents over-winding. In uppermost position of the float the measuring drum is automatically
locked. After unlocking of the measuring drum, the float descents with constant speed to the
cargo surface or tank-bottom. The float descent speed is controlled by a regulator (paddle
wheel) which rotates in the oil of the spring-motor compartment. This compartment is filled
with approx.7 liters of oil. The oil serves not only the regulator, but also lubricates the springmotor, provides a condense-free level display window and inhibits corrosion.

1.3
Accuracy
The accuracy of the 807 series marine level gauges is determined by the following factors:
a) The accuracy of the circumference of the measuring drum. The effective circumference of
the measuring drum is 600 mm with a tolerance of ± 0.02 mm.
b) The accuracy of the measuring cable diameter. The measuring cable is multi-stranded with
a central core. The diameter has a max. tolerance of ± 0.02 mm.
c) The weight of the suspended amount of measuring cable. The measuring cable has a
weight of approx. 1.3 g/m.
d) The hysteresis of the measuring system. The hysteresis is the total friction of bearings,
regulation, indicator, etc. The parts housed inside the spring-motor compartment add very
little to the hysteresis as they run under optimal conditions under oil, i.e. well lubricated,
no corrosion influence. The measuring drum runs under more severe conditions which
require a suitable approach. Depending on the type of tanker or application, measuring
drum bearings will be selected for their typical operational conditions. Depending on the
selection of the type of measuring drum bearings, the hysteresis may vary from a
maximum allowable 40 g (measured at the measuring cable as top-top-value) to only 10 g.
e) The accuracy of constant torque output of the spring-motor. The spring-motor has a linear
character with a tolerance of ± 10 g (measured at the measuring cable).
The density of the cargo influences the buoyancy of the float or the displacer. In light
cargoes the float will sink deeper than in heavy cargoes. See float immersion diagram.
f) The size and type of float used. Small diameter floats are more influenced by change of
density than larger diameter floats. See also float immersion diagram.
g) The cargo- and tank temperature can influence the accuracy of the measuring system,
particularly if the tank material is different of that of the measuring cable and measuring
drum. The difference in thermal expansion co-efficient of different materials causes
measuring errors, but these may be partly compensated by way of mounting construction.
h) The temperature compensation diagram indicates maximum possible measuring errors,
caused by measuring wire expansion.
Considering only the factors a., b., c., d. and e. the accuracy of the measuring system can be
expressed in the following formula:
ΔL = ± (2.0 + 0.15 l) mm
ΔL
l
= Accuracy
= Suspended length in meters
(l is the amount of suspended measuring cable in meters). For factor d. the maximum
allowable hysteresis has been used.
For initial adjustment of the level gauge it is recommended to set the local indicator so, that
the float or displacer is set for average immersion level (see float immersion diagram).
Tankers carrying cryogenic cargoes (LNG etc.) may be fitted with level gauges with Invar
(36% nickel steel) measuring drum and measuring cables.

2 Mounting
2.1
Mounting of level gauges, general
The mounting flange of the HSH 807 series marine level gauge is compatible to:
6" 150 lbs ASA r.f. flange
DN 150 PN 16 flange (DIN 2502)
10K DN 150 JIS flange
other flanges, such as 6” 300 Lbs, DN 150 PN 25/40 or JIS 20K DN150 are optional
The display window of the local indicator should face aft, same as the hand-crank of the float
hoisting mechanism.
To have free access to the level gauge internals, for maintenance and calibration, it is
recommended to have a free area with a radius of at least 1.5 to 2 meters around the level
gauge.
Trim or list of the ship has practically no influence on the accuracy of the level gauge.
2.2
Liquefied gas tankers
According IMO resolution A.328 (IX)
each cargo tank should be fitted
with at least one liquid level gauging
device.
Where only one liquid level gauge is
fitted, it should be arranged so, that
"any necessary maintenance" can be
carried out while the cargo tank is in
service.
For float-type liquid level gauges,
"any
necessary
maintenance",
includes inspection of the float and
therefore it is recommended to
mount the level gauge on a full bore
ball valve or gate valve, which
allows free passage of the float (see
fig. 19).
By using a float with a diameter of
125 mm the valve size can be
generally limited to 6" ASA 150 lbs
R.F. (or NW 150 ND 16). In most
cases a perforated pipe will be
required for float guiding. With a
level gauge mounted above a ballor gate valve it must be checked
that the float is above the valve
before closing the valve. Failure to
do so will result in damage of float
and/or measuring wire.

3 Commissioning
3.1
Spring motor adjustment
Next, check the correct operation and setting of the spring-motor. Release the float, applying
a braking force to the spring-motor manually, all the way down until it reaches the tank
bottom. Meanwhile, check that the torque output drum (fig. 5 item 46) rotates anti-clockwise
(facing the spring-motor compartment) and the spring-storage drum rotates clockwise (fig. 5
item 45). If the float stops during its downward movement before it reaches the tank bottom,
check that sufficient spring tape is left on the storage drum.
If this is not the case, rotate the torque output drum (main shaft) 3 revolutions in clock-wise
direction by hand and lock the spring-motor by the engaging the float hoist mechanism. While
rotating the torque output drum, check that the storage drum rotates anti-clock-wise (1800
mm on the local indicator). After the spring-motor has been locked, rotate the measuring
drum in a clock-wise direction (facing the drum compartment) until the float reaches the tank
bottom. Because the magnetic coupling of the measuring drum provides a counter force to the
manually applied rotation force, it may be necessary to remove the drum from the shaft in
order to prevent too high radial forces on the shaft. When the float has reached the tank
bottom, dis-engage the float hoisting mechanism and check that the float is still resting on the
bottom.
Hoist the float and release it once again, adjusting the speed carefully by hand. The vertical
speed should be almost constant.
3.2
Local level indicator setting
To set the local level indicator, the float must be placed at a known level (tank-bottom, liquid
level or valve top). Compare the known level with the actual read-out of the local level
indicator (fig. 4 item 61). During initial installation it is obvious that the factory setting is not
similar to the required setting. To obtain an accurate setting the fixing screw of the local
indicator (fig. 4) must be unscrewed. Pull out the local indicator and set it (approx.) to the
required setting and fit it back into its position, so that the drive gear and indicator gear are
not yet engaged. Now make the final setting (setting accuracy 2.5 mm) and fix the local
indicator home, making sure that the gears are correctly engaged. Fasten the local indicator
by tightening the screw.
3.3
Reference switch and level alarm switch (if fitted)
Level gauges with intrinsically safe level transmission and digital remote level readout can be
fitted with 2 level alarm switches and a reference switch. The reference switch is required
when a level transmitter is fitted. The reference switch gives the "start" signal for the remote
level indicator and ensures, during operation of the level gauge, synchronization of the local
read-out and the remote read-out. Reference switch and level alarm switches are designed for
NC (normally closed) circuit. The level alarm switches are optional when level transmission is
fitted and can be connected to several types of HSH AMTG series remote level indicators.

USER MANUAL FTLG 807 (0112)
3.4
Switch operation
The reference switch must always be set to open when the float reaches the highest point
(against float stops, against the mounting flange or above the valve). This means that the
switch is closed from the moment the float is released and the level gauges thus in operation.
A high level alarm switch must be set to open when the cargo level has reached the required
level. Under this level the switch must be closed.
A low level alarm switch must be set to open when cargo level has reached the required level.
Above this level the switch must be closed. (This is contrary to the high level or reference).
The construction of reference switch, high- and low level alarm switches is identical: a
magnetically actuated "reed" contact. The "reed" contact is fitted on a printed circuit board.
The complete print board is fitted at the switch frame. A small magnet is fixed in the last digit
wheel (at the 2 o’ clock position).
During non-alarm condition the magnet must be positioned directly in front of the embedded
"reed" contact. In this position the switch is closed (normal condition). At the required level
setting the magnet turns away from the "reed" contact, thus opening the switch.
Remark: The turning direction of the spring-motor for setting high level alarm and
reference is clockwise. For low level alarm the turning direction is anti clockwise.
3.5
Switch setting
Turn the spring-motor by hand until the local read-out shows the required level alarm setting
(for level alarm switches) or until the float has reached the highest point (just about to touch
the float stops or mounting flange or just above the valve). Hold the level gauge spring-motor
at this level. Slack the fixing screw of the switch.
Pull out the switch from its fixed position by turning it slightly to the left. (Bayonet fitting).
Turn the driving (first) digit wheel so that the magnet in the last digit wheel is just on the
point of turning away from the embedded "reed" contact.
Turn the driving digit wheel always in the same direction as if it would be driven by the springmotor: for reference and high level spring-motor clockwise; for low level spring-motor anti
clockwise.
Fit the switch in place, making sure that the gears are correctly engaged. Tighten the fixing
screw and check the setting. Turn the spring-motor so that the float moves up and down.
For reference and high level the switch must be closed when the float is below the required
level setting and open above this point. For low level the switch must be closed when the float
is above the required level setting and open below this point.
The maximum setting accuracy is ± 2.5 mm. When the setting is not yet correct, slack fixing
screw and pull the switch so far out that the gears are just disengaged. Turn the driving digit
wheel just as many gear teeth as is required (observe correct turning direction) and fix the
switch again.

3.6
Level transmitter (if fitted)
The intrinsically safe level transmitter is designed to provide HSH AMTG series remote level
indicators with level information. The level transmitter consists of a gear driven rotor disc and
three inductive proximity switches.
The level transmitter does not require adjustments or setting.
The synchronization between local read-out and remote read-out is arranged by the reference
switch in the level gauge and reference program in the remote level indicator.
3.7
Oil filling
First fit the spring-motor compartment cover (fig. 3 item 7), making sure that no tools or dirt
remain in this compartment. Check that the oil drain plug is tightened (fig. 3 item 11) and fill
the spring-motor compartment with oil up to the oil fill plug level (oil fill plug fig. 3 item 11).
At this level the oil can be seen through the read-out window. Close the oil fill plug and fit the
measuring drum cover. The level gauge is now ready for operation.
3.8
Starting-up
The measuring drum and float are already fitted in the factory and after the adjustment of
local indicator and, if fitted, the reference switch and the level alarm switches, the level gauge
can be closed and the instrument is ready for operation.

4 Operation
4.1
Operation with manual float hoisting mechanism
The operation of the level gauge is very simple. To hoist the float, simply place the hand crank
(see fig. 3 item 90) on the shaft at the spring motor compartment and rotate slowly clockwise. The magnetic coupling of hand crank and hoisting mechanism prevents over-winding.
When the float has reached the highest point (against float stops) the hand crank slips
through the magnetic coupling.
Check the local read-out level. At the highest point of the float the level gauge is automatically
locked. After the float is hoisted the hand crank must be removed. To start measurement the
float must be released from the hoisted position. Engage the hand crank and turn 1 (one)
revolution anti clock-wise. Remove the hand crank when the float is released. Float release is
visible at the local read-out.
Check the oil level at regular intervals (e.g. every month). A too low oil level will result in an
excessive float descend speed. Normally the oil level is visible through the local read-out
window.
5 Maintenance
The oil filling of the level gauge should be renewed preferably once every 5 years. Always use
clean oil for filling. The minimum and maximum oil level can be checked by removing the oil
fill plug. Minimum level is at the lower edge, maximum is at the upper edge of the fill pipe
stud.
Once every 5 years the terminal box should be checked for moisture. If silica gel sachets are
present, either renew or regenerate these.
The bearings of the level gauge should be checked, and if necessary renewed, every 5 years.
At the same time check the measuring cable and float for corrosion.
WARNING
Never remove a measuring drum before locking the spring-motor. Failure to do so will
unwind the spring-motor and cause severe damage. The oil in the spring-motor
compartment does not have to be drained in order to lock the spring-motor. Fit the
measuring drum in exactly the same position as it was taken out, e.g. with the float at the
same level. If this is done correctly, re-adjustment of the level gauge is not required.
DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE IS PRESENT.
