Load fields from a node which reference an entity
You can use entity_metadata_wrapper() to easily get referenced entities, their field and much more.

$node_wrapper = entity_metadata_wrapper('node', $entity);

foreach ($node_wrapper-&gt;field_products as $product_wrapper) {
  // You can print or do whatever you like with the value of the fields 
  // of the referenced entity like below:
  print $product_wrapper-&gt;field_flow_rate-&gt;value();
}
