    Does SW keep track of time spent.

    Take a look at ManicTime (do a web search) this records time against a number of attributes. Its been a while since I used this but it was stable in Win7 and gave quiet a lot of info for usage. Regards

    System Recommendation

    I'm after a new system and need some pointers on the eternal question of #32 bit vs. #64 bit, operating system and how many cores. I imagine time passes quickly in the processor/system world and previous posts' issues re operating systems and hardware get sorted. Turning Intel processor...

    Diaphragm Actuator and Membrane Actuator. Is it similar?

    I'm shooting from the hip on this, my sense of this is. A diaphram can be something like a top hat in geometry providing a long stroke for the diameter. The shape can basically turn itself inside out in realising a full stroke. In contrast a membrane conveys more of a flat disk where the stroke...

    Heating Limit of Bunker 'C' or HFO

    Thanks all for the posts. I want to read further on the fuel systems (pumps, meters, burners, and heating) for marine boilers and engines especially when it comes to the use of heavy fuel oils. The demands of the environment especially regarding equipment is of particular interest. Can anyone...

    Heating Limit of Bunker 'C' or HFO

    For marine boilers what temperature is Bunker oil brought to before entering the burners. Is there any limit imposed by the equipment used or oil itself. Whats recommended and does practice look to exceed these for better cost/effeciency? Could any one provide some reference sites to read up on...

    4-20mA Loop Powered Sensor/Transmitter Calibration

    Sounds like calibration should remain unaffected providing: - local wiring and power of loop are within manufacturers limits of voltage and loop resistance. - the range of the instrument has been specified and been calibrated to this. - handling and fitup do not strain sensor body. These all...

    4-20mA Loop Powered Sensor/Transmitter Calibration

    Thanks, Does factors such as the powering of the loop, shielding or wiring resistance affect the need to tweek the transducer for local conditions; or should the local setup be to a standard that removes need for adjustment for these factors.

    4-20mA Loop Powered Sensor/Transmitter Calibration

    Does a calibrated 4-20mA Loop Powered Sensor/Transmitter wired into its circuit 'fresh out of the box' require tweeking to allow it to turn the input pressure/temp/flow value into a reliable 4-20mA signal proportional to the measured variable (as per calibration). This signal being read at...

    Self Employment Fee Scales

    Take a gander at the pie chart in the attached web page; although its Aussie the principle may/should be applicable. Best of luckhttp://www.apesma.asn.au/newsviews/professional_network/2003/dec_jan_03/contract_rate.htm

    MathCad Vs Alternatives ?

    Any advice or opinions on alternates to mathcad. I used the program many years ago as well as TK Solver. Major Pros and Cons would be great. Thanks in advance

    Non Ferrous in Low Pressure Designs

    I am looking for advice regarding aluminum flow hardware such as simple valves, strainer housings and diverters (swept shapes with multiple outlets and flanges) in low pressure <150PSI fuel oil applications i.e. for diesel and kerosene. I see these materials used in road tanker flow 'jewelery'...
