Ship's trim and list measurement
A pair of solid state, inclinometers installed 90° with respect to each other, measure bow <> stern and port <> starboard angles
See inclinometer

Centralised Display
TankView software provides centralised indication, alarm and control of all tanks. Repeater displays provide function critical information at additional locations
See TankView
See VPM 4300

Local visual indication of tank level
KD level gauges with flat or reflex glass provide a direct view of the level inside lubricating oil or boiler water feed tanks
See KDLG
See KDMLG

Overfill protection for waste water / oil storage
KD 30 level switch used to detect a high level condition in bilge and service tanks
See KD 30

Day tank fuel oil measurement in engine room
Self-powered HCG contents gauge provides a local continuous indication of tank level with a KD 12 level switch used to detect a low level condition
See KD 12
See HCG

Bunker fuel oil measurement in engine room
ict 1000 level transmitter with flange mount installed at the base of the tank via an isolating valve as isolation from potential high temperatures
See ICT 1000

Cargo tank level or volume measurement
An advanced pulse radar sensor providing high performance with low maintenance needs. Compact design with no intrusive sensor dome ensures simplicity of installation.

Level detection in bilges and void spaces
BLS 9200 bilge switches detect the rising level of water or oily waste as part of a pump control or flood detection safety system
See BLS 9200
See Bilgesafe

Cargo tank overpressure and vacuum measurement
ict 1000 with a direct pressure calibration measures the cargo tank inert gas blanket directly or in the vent manifold
See ICT 1000
See VentSafe

Wing ballast tank measurement
ict 1000 level transmitters are installed at the bottom of a stilling tube with cable exit via a deck penetration flang
See ICT 1000

Double-bottom ballast tank measurement
ict 1000 level transmitters are installed using a clamp mount with cable exit via a liquid-tight bulkhead penetration
See ICT 1000

Ship's draught measurement
ict 1000 level transmitter installed inside a vented draught tube is used to measure the ship’s depth in the water
See ICT 1000
