what is the suitable densitometer that apply for cement slurry and can be mounted undersea..this is for grouting job. either its diver probe or attached to the pipe.
Try addressing a query to LEMIS Process. They have supplied density meters for slurries and are a flexible company who can address the needs with far less hassle than some other companies so if there isn't a product for underwater they are a good bet to develop one if there is sufficient market.
