Important TS1 Installation Issues
1. The sender must not be mounted closer than 150mm from the
centre of the sender to sides of the tank, baffles or other intrusions.
2. Only use on tanks greater than 200mm in depth.
3. Sender must be mounted parallel to the surface of the liquid.
4. Do not install on flexible tanks that may bulge/distort as fluid levels
change.
5. Check unit is calibrated to suit tank shape, depth and fluid type.
6. Make sure that sender protrusion is NOT in contact with any
object including sealants when mounted.
7. Use gasket and fittings as provided.
8. Mount above deepest point of the tank.

Note: Liquids that may have a sound absorbing surface will limit tank depth or in the worst
case provide no return signal eg. foam bubbles or porous sludge.
Permanent liquid surfaces that are more than 3 degree’s off level will have a tank depth derating effect.
Liquids that have higher viscosities than water (e.g. oil) may not propagate liquid ripples that
create a strong return signal. This will also have a tank depth de-rating effect.
Don’t use on tanks shallower than 200mm in depth as angular reflections will reduce
accuracy.

The acoustic protrusion should be positioned in the tank aperture in the centre of the
hole. The protrusion should ideally be protruding into the tank and not be recessed in the
hole. See drawing above.
For tightening screws ensure base and washers are sitting flat. Tighten screw until screw
head makes contact with the washer, and then tighten another 2 full turns.
Maximum torque for the mounting screws is 0.5 Newton meter.
Note: Drawing is not to scale. Please use the tank gasket as a template and make sure
the tank hole is 42mm.

Case 1
TS1 must be mounted at the deepest tank point!
It is recommended the sender is mounted in the middle of the tank, this is particularly
important on low or no baffled tanks that are mounted in moving vehicles or vessels. This
allows the TS1 to average waves of fluid to the correct level when the depth is varying due to
wave slop.
Case 2
TS1 must be mounted at least 150mm from a vertical tank baffle, tank walls and piping.

Case 3
Correct BEP Gasket must be used!
Use 5 washers provided, washers must be placed under screw heads to prevent rubber lid
damage.
Case 4
Acoustic protrusion must not touch the tank frame!
Case 5
TS1 must be mounted so it can see the bottom of the tank if the liquid is to be measured to
the bottom.

Case 6
Inlet and Outlet piping must go in at least
⅔rds of the way in to the tank on grey and black
water tanks to stop water turbulence when filling.
Case 7
Do not fit the TS1 with a tube.
Case 8
Ensure bolts and mounting holes are aligned properly to keep plastic body isolated
acoustically from tank. Do not over tighten the screws.

5. Wiring
Power must be removed before TS1 is connected to the system. Ensure wiring is
correct or else damage may occur rendering the device inoperable.

Please visit the BEP website for the programming software.
7. Problem Solving
Water Tanks
After long periods of no use, condensation will build up on the roof of the water tank and the
sender face. If the water droplets are large, the sender will not be able to read the contents
of the tank accurately. This will clear with normal boat or RV use.
Waste Tanks
Large amounts of foam bubble on the surface of the liquid caused by detergents or washing
powders will result in the sender not receiving reflected sound pulses back from the liquid
surface, instead these will be absorbed by the bubbles until they disperse. Then normal
operation will resume.

8. Frequently Asked Questions
Q: What is the signal update period?
A: Signal is updated in real time.
Q: Why is the tank level stuck on one value?
A: When the sender cannot measure a valid tank level, the sender will recover the last good
reading of the tank level from its own memory. This will be sent to the monitor until a new
valid level is found.
Q: Is the TS1 ignition protected?
A: The TS1 is ignition protected and approved. It is fully potted.
Q: On power up, the analogue gauge goes full scale then back to empty. After 5 seconds it
shows the correct level.
A: This is normal for a 10 – 180ohm analogue gauge.
Q: On power up, the analogue gauge goes full scale and then back to the correct level.
A: This is normal for a 240 – 33ohm analogue gauge.
Q: The gauge is reading full all the time.
A: 1. The most common problem is that the acoustic protrusion is touching the tank.
2. The incorrect gasket has been used specified gasket is a Cork/viton mix.
3. The sender is to close to the side of the tank.
4. There is an obstruction in the tank.
5. The mounting screws are not isolated acoustically from body (see. Case 8)
Q: Is the sender sensitive to electrical interference. Should we use shielded cable?
A: There is no need to use shielded cable, unless you are running a long distance and near
appliance cables that radiate noise.
Q: What is the maximum distance between sender and meter?
A: 50 metres.
Q: What support is there for the product?
A: Updates will be placed on BEP website.
Q: Why is the meter reading incorrect when tank is empty?
A: There must be some fluid covering the bottom of the tank for sender to receive a valid
return signal.
Q: What is the beam angle of the sender?
A: 300mm at 2M depth
Q: Can I use a sealant with the TS1 and gasket
A: Yes, but ensure sealant does not get on to protrusion. Also, do not over tighten screws
for purpose of providing a tighter seal. The screws should be tightened until there is
contact between screw head and washer, then another 2 full turns.
