Shaft Power Thrust Meter

Since many years VAF Instruments has been the expert in the field of maritime measuring equipment. The upcoming new IMO regulations and the effectiveness of SEEMP** legislation on 1st of January 2013 have inspired us to develop the next step in our successful line of sensors: the TT-Sense Shaft Power Thrust Meter.

Using the TT-Sense for measuring shaft speed, torque and power results in broad insights in your propeller efficiency, vessel pitch optimization and hull resistance. 

The TT-Sense is using the latest techniques to contribute to ship power management. The actual thrust measurement is obtained through an extremely accurate optical sensor technology. As a result of this non-contact sensor technology, the TT-Sense thrust and torque measuring system is maintenance free.

Propeller efficiency by thrust and torque measurement

Thrust measurement provides you with precise information on propeller efficiency in relation to the energy consumed. The effects of operational changes on the actual thrust, speed, torque and power are immediately visible on a separate (touch) screen. By using this input, your propulsion installation can be used in the most efficient way. Consequently this will reduce the fuel consumption considerably!

Since the fuel costs will be reduced remarkably, the ROI will only be a few months. VAF's shaft power thrust meter can be installed easily on both new building and existing vessels.

Besides the standard output of a thrust, torque, shaft speed and power signal, the TT-Sense can be combined with VAF fuel consumption flow meters. Moreover, the TT-Sense can be extended with energy consumption and propeller shaft analysis. All in order to gain an even larger efficiency!

The TT-Sense holds the following benefits to help you reduce fuel costs:

Very high accuracy and repeatability

Propeller thrust and hull analysis possible

Pitch optimization

Cavitation detection

In line with SEEMP** regulation 

No time consuming mounting of strain gauges

User friendly interface
