Page 17 Enter the flow rate Enter the average particle size, and the system then calculates the calibration factor. This figure can be modified with choice 3 Edit Factor. Be careful changing the factor as it can change the weight figure dramatically. It is best to stick with Auto Calibrate unless a known weight of sand is being produced and the system is calibrated at that time. Edit Factor Screen, it is not recommended to change the calibration factor unless you are sure it is necessary and understand the consequences. 4. and 5. File Handling and Event Log are not f ...

Page 7 Threshold Threshold c - High Flow, No Sand d - High Flow, With Sand The SandAlert Lite unit eliminates the flow noise by placing a threshold automatically just above the flow related noise signal, and if the signal goes higher than this then it is due to solid impacts, which can be seen in b and d as short duration, high energy spikes, as compared with the flow related noise that is longer duration, and of lower energy. The threshold is visibly higher in d, due to the higher level of flow related noise. There is also an option with the SandAlert Lite to utilis ...

Page 9 Where vibratory conditions exist it is recommended that a thread locking adhesive is used. Also it is important to ensure that the free end of the chain is cannot fret against the clamp or the pipe, by tying it up with cable ties. The PULSARguard 2001 is fitted using stainless steel banding (11mm wide), you can either use a re-usable “jubillee” clip type toothed band, or by a plain band with crimpable clips. All the above points regarding position and surface preparation above apply. Always ensure that the pipe is cleaned to bare metal and that the silico ...

Page 4 The sensor housing is rated at IP68 giving protection against temporary immersion to a depth of 3 metres. The sensors are powered from a power supply via a galvanically isolated safety barriers, in the SandAlert Lite unit. The sensors are attached to the outside of the pipe, on or just after a bend, by means of a universal pipe diameter (3" to 8") stainless steel sensor/pipe clamps. The sensor is connected to the SandAlert Lite via in-line connectors and a 100 metre extension cable, although it can be extended to 1000 metres if required. Note: The Pulsarguard ...
