Title: Improvements in or relating to the measurement of mass flow rate of gases
Inventor: MCLACHLAN KENNETH ROY
IPC: G01F1/90
Filed: 1965-04-02
Abstract: 1,086,628. Measuring mass flow rate of gases. WESTWIND TURBINES Ltd. March 10, 1966 [April 2, 1965], No.14026/65. Heading G1N. The mass rate of flow of a gas is measured by integrating square pulses having a repetition frequency, duration and amplitude linearly proportional to a respective one of the quantities volumetric flow rate, pressure and the inverse of the temperature of the gas. The gas flows past a turbine having gas lubricated bearings, causing it to rotate at a speed proportional to the volumetric flow-rate of the gas thereby generating pulses at a corresponding frequency by means of a magnetic or capacitive pick-off. These pulses after shaping are supplied to a bi-stable circuit to generate a further series of pulses of the same frequency. Each of the latter pulses is terminated by a feedback circuit including a time constant circuit and a level discriminator supplied with signals from the time constant circuit and from an amplifier connected to a copper resistance thermometer (or a thermocouple). The length of the pulses is thus made inversely proportional to the gas temperature. The pulse amplitude is then controlled in accordance with the output of a further amplifier receiving the output from a diaphragm-type pressure transducer including a strain gauge or an inductive pick-off. The resulting pulses are finally supplied to a moving coil meter. The output may be modified as a function of standard pressure and temperature so that the device indicates the flow rate in units of standard volume for a particular gas. The measuring circuit may also include means for modifying the output in accordance with a selected value of R, the gas constant, so that the device may be used for any gas.

[Also in Division H2] An installation for feeding successive batches of materials in proportionate quantities and mixing them is shown in the state in which the mixing tank M is full of mixture which is being agitated by a stirrer driven by the motor MMO. Manual operation of the push-switch PPS, or closure of the pressure switch T4 by fall of level in the tank T, energizes the solenoid PMG to change over the switch P to the position shown, which stops the motor MMO and energizes solenoid MMG to open discharge valve M1 After a predetermined time interval, time switch MTC de-energizes MMG and allows spring M7 to close valve M1 and switch S, which changes over switch P (PMG having been de-energized by time-switch PTC<SP>1</SP>), closing switch PS<SP>1</SP> which in turn causes change-over of switch Q (QPS being closed). This starts the motor DMO to open the liquid supply valve D1; the motors AMO, BMO, operating the screw feeders A1, B1 for powder material ; the mixer motor MMO; and the motor FMO to lower the float control F4 into the mixing tank. The quantity of liquid supplied is controlled by the float F4 and that of powder by the time switches ATC, BTC, and upon their operation the state shown in the drawing is regained. If the switch QPS is left open, powder only will be supplied. If powder is to be fed to the mixer tank before the liquid, a pressuresensitive device responsive to the weight of powder may be used in the mixer tank instead of the float device.
