A modular ultrasonic flow meter including a substantially watertight meter housing connected to a flow tube; a measurement printed circuit board including a measurement circuit communicating with one or more ultrasonic transducers, arranged in the meter housing for transmitting and receiving ultrasonic signals; and a self-contained power supply. The ultrasonic flow meter further includes a control module comprising a module housing connected with a main printed circuit board including a central processing unit, a memory circuit and a communication circuit, and a power- and communication connection is provided between the main printed circuit board of the control module and the measurement printed circuit board whereby the self-contained power supply may power the main printed circuit board and the measurement printed circuit board.

A method for controlling a filling process, wherein a predetermined filling quantity of a medium is filled into a container, the flow rate of the medium flowing into the container is measured as a time series of measured values for the instantaneous flow rate and a filling quantity already filled is estimated from the time series, wherein at least one current measured value of the time series is corrected on the basis of at least one earlier measured value of an earlier time series of measured values of the flow rate of an earlier filling process.

A dispensing device which has a dispensing channel extending between a supply opening and an output opening into the course of which a pump, a selection valve and a dispensing valve are connected. The selection valve is also connected to a pressurised air source. The dispensing device allows a dispensed output of a fluid, wherein a buffer channel portion is filled by the pump in a pump dispensing phase, to which buffer channel portion pressure is applied from the pressurised air source during a pressurised air dispensing phase such that a precise fluid output is subsequently possible by clocked actuation of the dispensing valve until the target fluid amount has been reached.

The present invention relates to a measuring device (10) and a method for determining a depth of field of an optical structure (100). In this case, the measuring device comprises a device body (12) with a measuring axis (14), the device body (12) being formed such that, in a measuring position, it can be placed in a stationary manner on a deposit plane of the optical structure such that the measuring axis (14) of the device body (12) coincides with an optical axis of the optical structure, wherein the device body (12) has a measurement scale (18) arranged along a scale line (16) such that the scale line (16) encloses with the direction of the measuring axis (14) a scale angle φ greater than 0° and less than 90° and the measurement scale (18) can be optically detected in the measuring position of the device body (12) by the optical structure (100) for determining the depth of field.

A fluid flow rate sensor, which may also be the basis of a valve for a fire suppression system, uses a sensing arm to convey motion of an obturation body or a valve closing member to a sensor system which evaluates the motion and generates a calibrated measure of the flow rate and/or an alarm signal in response if warranted. The obturation body and the valve closing member are capable of both rotation and translational motion, both of which are sensed using the sensing arm. The sensor system is isolated from the fluid within the valve.

A fluid control system and associated method for pulse delivery of a fluid includes a shutoff valve and a mass flow controller (MFC) upstream of the shutoff valve. The MFC includes a flow channel, a control valve to control flow of fluid in the flow channel, a flow sensor to measure flow rate in the flow channel, and a controller having a valve input from the shutoff valve indicating opening of the shutoff valve. The controller is configured to respond to the valve input to control flow of fluid through the control valve to initiate and terminate a pulse of fluid from the flow channel to the shutoff valve to control a mass of fluid delivered during the pulse of fluid. The valve input can be a pressure signal, and the MFC can include a pressure sensor to sense the pressure signal.

A method of determining vapor pressure of a fluid is provided. The method includes the steps of providing a meter (5) having meter electronics (20), the meter (5) being at least one of a flowmeter and a densitometer, and flowing a process fluid through the meter (5). A pressure of the process fluid is measured. The pressure of the process fluid is adjusted until a monophasic/biphasic boundary is reached. The flowing vapor pressure of the process fluid is determined at the monophasic/biphasic boundary.

An agricultural vehicle includes a coupling structure for making a tool-less attachment between a first connector piece and a second connector piece. The first connector piece has at least one pin, and the second connector piece has at least one slot adapted to receive the pin in a receiving pocket that is circumferentially spaced from an axially-open inlet portion of the slot. The slot includes an inlet ramp between the slot inlet portion and the receiving pocket, and the inlet ramp is less steeply angled than a second ramp surface that forms a portion of the receiving pocket adjacent the first ramp.
