Abstract:
A consumption meter is provided with a conductive feed through for external communication equipment. The meter comprises a housing (104) which forms a closed compartment when an opening of the housing is closed with a cover (106). The compartment includes a communication module (204) and the conductive feed through comprises at least one conductive path (202, 408) from the communication module (204) to an outside part of the meter (102), which outside part is subject to ambient conditions. The path is provided via the opening of the housing and a sealing means (210) in the opening of the housing is used to seal against a first surface (308) of the conductive path when the cover is attached to the housing.

Abstract:
The invention relates to an ultrasonic flow meter arranged to measure a flow rate of a liquid, the flow meter comprises a flow tube 2, optionally a measurement insert, and two or more ultrasonic transducers 8 which are arranged in transducer inserts 20 to be inserted into the flow tube through openings in the flow tube. The transducer inserts are formed monolithically with the housing as a part of the bottom of the housing. The transducer inserts are in a mount position inserted through the openings in the flow tube to extend into the flow passage so that the surface 15 of the transducer inserts protrude into the flow passage. In this manner, gas bubbles, such as air bubbles, released from the flowing liquid will not rest in front of the transducer insert irrespectively of the orientation of the flow meter in the pipe installation.

The internal transducer housing element and/or the external transducer housing element are arranged to extent through the transducer hole in the wall of the tube and to engage. Whereby the transducer housing is fixated to the tube. The main housing is arranged to engage with the transducer housing to constitute a closed meter housing.
Abstract:
A turbidity measurement device for measuring turbidity of a fluid flowing in a flow tube. A first transducer transmits ultrasonic signals through the fluid in the turbidity measurement section so as to provide a first ultrasonic standing wave between the first and second section ends. A receiver transducer receives the ultrasonic scattered response from particles in the fluid flowing through the turbidity measurement section. A control circuit operates the transducers and generates a signal indicative of the turbidity of the fluid in response to signals received from the receiver transducer. Preferably, the device may comprise a second transducer for generating a second ultrasonic standing wave with the same frequency, and further the two transducers may be used to generate a measure of flow rate by means of known ultrasonic techniques. This flow rate may be used in the calculation of a measure of turbidity. Both turbidity facilities and flow rate facilities may be integrated in a consumption meter, such as a heat meter or a water meter.
