Transmitter for providing inventory or inventory transfer information on a product in a container
First Claim
1. A transmitter for measurement of mass, weight, volume, level and/or density of a product in a vessel, comprising:
- a level sensor, comprising;
a conductive probe extending into the vessel, means for generating and sending short electromagnetic pulses down the probe, means for reception of echoes of the pulses reflected at a surface of the product, and means for determining a time of flight needed for a pulse to travel down the probe and its echo to return;
an optical fiber as a temperature sensor which is integrated in said conductive probe;
at least one optically analysing pressure sensor, mounted on said conductive probe; and
a signal processing unit for determining mass, weight, volume, level and/or density based on measurement signals supplied by said level sensor and said at least one optically analysing pressure sensor.

Abstract
A transmitter for providing inventory or inventory transfer information on industrial sites is described, for measurement of mass (M), weight (W), volume (V), level (L) and/or density (p) of a product (1) in a vessel (3) comprising: a level sensor (5), comprising: a conductive probe (9) extending into the vessel (3), means (11, 13) for generating and sending short electromagnetic pulses (S) down the probe, means (15) for reception of echoes (E) of the pulses (S) reflected at a surface of the product (1), means (17) for determining a time of flight (t) needed for a pulse (S) to travel down the probe (9) and its echo (E) to return, a pressure sensor (7), mounted on the probe (9), and a signal processing unit (45) for determining mass (M), weight (W), volume (V), level (L) and/or density (p) based on measurement signals supplied by the level sensor (5) and the pressure sensor (7).
