Level of emulsion with 7mm dia solid particles

Is it possible to measure the static head pressure of an emulsion containing solid particles ~7mm diameter?

If there is significant fluid movement you may need to support and protect the sensor and cable from damage. To prevent the solid particles touching the sensor diaphragm, we would suggest keeping the nose cone fitted. However, if the emulsion has a high viscosity this may lead to clogging of the nose cone. This will prevent the static head pressure being applied to the sensing diaphragm. The nose cone should be regularly inspected and cleaned when necessary to remove any sign of clogging.
