摘要： A flow-rate monitoring system may include a position sensor, a strain gauge, and a computing device for determining a rate of fluid flow through a pump using strain measurements. The strain gauge may determine strain in the chamber. The position sensor may determine the position of a crankshaft coupled to a plunger in the chamber. The computing device may receive signals generated by the strain gauge and the position sensor related to the strain in the chamber and the position of the crankshaft and process the signals to determine a flow rate through the chamber of the pump.

摘要： A small volume prover apparatus and method for precisely measuring the displaced volume of a fluid. A precision bore cylinder and a piston can be configured with a valve arrangement in order to permit fluid to pass through an annular passage when the piston travels from one position to an opposite position. A magnetized forcer connected to the piston and a magnetic drive chamber configured to produce linear motion of said magnetized forcer are operably connected to the piston in order to move the piston from one position to the other.

摘要： Flow sensors are provided that can provide both leak detection and flow monitoring. The flow monitoring enables a determination whether there are blockages or leaks in a fluid system during normal operation of the system. The leak detection enables detection of leaks when the system is shut off. The flow sensors can use a frusto-conical flow guide to provide a more compact flow sensor.

摘要： A Positive Displacement Metering Systems (PDMS) using a Water Fill Cylinder (WFC) is provided. It will replace or be paired with an existing conventional water meter. The primary advantage of the PDMS is its ability to detect and measure “micro” flow rates. The PDMS allows the water utility to bill for all water consumed by the customer. The PDMS will only allow 100% detectable flow rates to pass through the water meter attached. Flow rates which are undetectable, or only partially detectable will be accounted for. The PDMS will report the sum of the two meters to the utility. The PDMS will also function as a leak detection device and water conservation tool, will perform automatic or remotely controlled functions like turning off water, when a high flow leak is detected, and report directly to the water utility or tenant of the property being monitored.

摘要： System for determining the flow rate of a fluid and for controlling flow rates. The system provides high resolution with infinite turndown, providing a flow meter which may be used in low flow situations and with fluid additives. The flow rate of an additive fluid is determined in real time with high resolution by providing a novel reciprocating positive-displacement flow meter using magnetically coupled components and a transducer to identify the flow rate of the fluid. A system and method may be incorporated into a flow control system for monitoring the flow rate of a fluid which may be included with an additive delivery system for use with the flowing supply of an additive to be introduced into a flow of untreated fluid in relatively minute quantities.

摘要： A measuring body is provided in a fluid path between a pump and a fuel injection valve, a flow amount for which is measured. An inner space of the measuring body is divided into a first and a second fluid chambers by a partitioning wall, wherein the first and second fluid chambers are, respectively, operatively connected to the pump and the fuel injection valve. A movable member (float) is slidably inserted into a through-hole formed in the partitioning wall, so that both ends are respectively exposed to the first and second fluid chambers. When the fuel injection is carried out by the fuel injection valve, the fluid in the second fluid chamber is decreased corresponding to the amount of injected fluid, and thereby the float is moved in a direction from the first to the second fluid chamber. The amount of the injected fluid is measured by detecting the movement of the float.
摘要翻译：测量体设置在泵和燃料喷射阀之间的流体路径中，其测量流量。测量体的内部空间通过分隔壁被分成第一和第二流体室，其中第一和第二流体室分别可操作地连接到泵和燃料喷射阀。可移动部件（浮子）可滑动地插入到形成在分隔壁中的通孔中，使得两端分别暴露于第一和第二流体室。当通过燃料喷射阀执行燃料喷射时，第二流体室中的流体相应于注入流体的量而减小，从而浮子沿着从第一流体室到第二流体室的方向移动。通过检测浮子的移动来测量注入流体的量。
