摘要： In a gas flow monitoring method using a MFC (a flow control device) for controlling a flow rate of process gas from a process gas supply source and supply the process gas to a predetermined process chamber, a start shut-off valve placed upstream of the MFC, and a pressure gauge placed between the start shut-off valve and the MFC, the start shut-off valve is closed and a drop of pressure on an upstream side of the MFC is measured by the pressure gauge to measure a flow rate of the MFC, thereafter, the start shut-off valve is opened to monitor the flow rate of the MFC. The MFC is switched from an ON state to an OFF state before the start shut-off valve is opened. The method enables in-line monitoring a low rate of process gas without affecting a semiconductor manufacturing process.

摘要： An external metering valve disposed on a gas fuel tank including an outlet rod is provided. The outlet rod includes an outlet orifice at a front end thereof. The external metering valve includes a metering valve and a gas guiding member. The metering valve includes a metering chamber. The gas guiding member includes a communication pipe, a blocking portion on the communication pipe, a discharging channel and an inlet orifice. The gas guiding member has a sealing outlet position and a metering outlet position. At the sealing outlet position, the outlet orifice outputs a gas and stores the gas in the metering chamber. At the metering outlet position, the blocking portion seals the outlet orifice through an airtight ring, and outputs the gas stored in the metering chamber through the inlet orifice and the discharging channel.

摘要： The waste liquid collection and transfer system includes at least one waste liquid transfer vessel that has a liquid input valve and a liquid output valve for controlling the flow of waste liquid therethrough. A pressurized gas liquid transfer system including at least one control valve is utilized to provide pressurized gas to said vessel to control the flow of liquid therefrom. A liquid drain line is engaged from the vessel to a liquid collection tank, and a liquid level alarm device is engaged to the tank to provide an alarm if the level in the tank becomes too high. An electronic system controller is engaged to the alarm device and to the various valves to control the flow of liquid throughout the system. When an alarm signal is received by the system controller the vessels are first emptied and thereafter allowed to become full, acting in this instance as additional waste liquid storage containers. When the vessels are full, the system controller shuts down the flow of liquid to the vessels. When the flow of liquid to the vessels is shut down by the system controller, it may then become necessary to shut down the chemical process equipment that generates the waste liquid.

摘要： A method and apparatus determines a quantity of liquid in a tank when at least one liquid sensor is inoperative. In a first embodiment, a plurality of tables are stored in memory which are grouped by identities of the possible inoperative sensor or sensors. One group of tables is selected based on the identified inoperative sensor or sensors. Then, that one group of tables is accessed, and the quantity of liquid in the tank is calculated based on the readings of the operative sensors. In a second embodiment, a first plurality of tables stores quantity readings for each sensor as if all sensors are operable. A second plurality of tables includes one table for each possible configuration of inoperative sensor or sensors. When the inoperative sensor or sensors are identified, one particular table in the second plurality is accessed and a quantity amount is then added to the liquid quantities determined from the first plurality of tables to provide a total liquid quantity in the tank. Preferably, all tables are loaded with liquid quantity values based upon studies emulating a variety of tank and liquid positional attitude.

摘要： A measuring cylinder into which liquid is supplied is provided with pressure transmitters for sensing the liquid pressure corresponding to the amount thereof. The pressure transmitters are connected with a pressure transformer to transform the pressure into an electric signal for controlling valves to stop and start the supply of liquid into the cylinder. The pressure transmitters are located in the cylinder at different levels and switched to be selectively operated in combination with the pressure transformer. In a preferred embodiment of the invention, the shape of the cylinder is designed so that the diameter thereof increases discretely from the lower part to the upper part thereof. One of the pressure transmitters is located at the bottom of the cylinder and the others are located at levels substantially the same as those at which the diameter of the cylinder increases.
