Fluid Counter

Hi

i am trying to find out the number of particles of water passing through a collider. 

Emitter produces 400 particulate water. Even if the collider touches all of them, the count remains around 200.

PHP Code:

   ObiSolver solver;
     [SerializeField] int counter = 0;

     void Awake()
     {
         solver = GetComponent<ObiSolver>();
     }

     void OnEnable()
     {
         solver.OnCollision += Solver_OnCollision;
     }

     void OnDisable()
     {
         solver.OnCollision -= Solver_OnCollision;
     }

     void Solver_OnCollision(object sender, Obi.ObiSolver.ObiCollisionEventArgs e)
     {
         var world = ObiColliderWorld.GetInstance();

         // just iterate over all contacts in the current frame:
         foreach (Oni.Contact contact in e.contacts)
         {
             // if this one is an actual collision:
             if (contact.distance < 0.01)
             {
                 ObiColliderBase col = world.colliderHandles[contact.bodyB].owner;
                 if (col != null && col.gameObject.layer == 7)
                 {
                     // do something with the collider.
                     counter=solver.contactCount;

                 }
             }
         }

     }
