This flowmeter is a clamp-on type ultrasonic flow meter based on transit-time measuring method.Making full use of the latest electronics and digital signal processing technologies, we realized a compact and light-weight design, and improved the accuracy and easiness to use while keeping with anti-bubble performance.The communication function (MODBUS: Option) is also applicable.)($785(61. Compact and light-weightThanks to the adoption of the latest electronics the flow transmitter size and mass are 1/3 of our traditional instrument.2. Full variety of sensorsThe flowmeter can be used with various types of sensors applicable for wide range of pipe size (ø13 to ø6000mm) and fluid temperature (-40 to +200°C).3. High accuracyThe flowmeter is designed for high accurary (better than ±1.0% of rate) by dynamic correction of fully-developed flow profile. Reynolds Number is calculated and a meter factor (K) is automatically applied for best accuracy at all flow velocities. Further, the adoption of new sound velocity measurement system permits measurements of fluids of unknown sound velocity. Moreover, affection from fluid temperature and pressure is negligible (Auto-Temp./Press. compensation).4. Excellent resistance against aerated flowFuji's unique ABM feature improves measurement reli-ability for different flow like slurries, sludge, raw sewage and bubble-contained flow (acceptable up to air bubble of 12% volume at 1m/s velocity).5. Quick responseWith the use of high-speed micro-processor suitedfor digital signal processing, the fast response time is realized.6. Multi-lingualThe following languages are supported for display:Japanese (Katakana), E nglish, German French, and Spanish.7.

3、将探头的高度值输入到“参考零点”，“参考零点”在菜单中的位置见附表三菜单结构图。

（探头高度为探头发射面到堰槽流水口的距离）4、标定“4mA流量值”和“20mA流量值”4mA流量值：瞬时流量等于这个值时输出4mA.20mA流量值：瞬时流量等于这个值时输出20mA.“4mA流量值”和“20mA流量值”在菜单中的位置见附表二菜单结构图。

5、选择量水堰槽的种类，要考虑渠道内流量的大小，渠道内水的流态，是否能形成自由流。

最大流量小于40升/秒（144吨/小时）建议使用直角三角堰；大于40升/秒建议使用巴歇尔槽；上游渠道较短，最大流量又大于40升/秒建议使用矩形堰。

使用仪表测量时要先标定参考零点，参考零点为探头到堰槽水位零点的距离。

（本仪表默认选择巴歇尔槽）①三角堰使用三角堰，可以在菜单“9堰槽类型”→“1三角堰”→“1工作状态”项选择“开启”，“2三角堰角度”选择实际角度仪表就可以根据水位自动算出水位对应的流量。

②矩形堰使用矩形堰，可以在菜单“9堰槽类型”→“2矩形堰”→“1工作状态”项选择“开启”，并且在“2标准渠道”中选择“0.25米、0.50米、0.75米、1.00米、非标渠道”，仪表就可以根据水位自动算出水位对应的流量。

③梯形堰使用梯形堰，可以在菜单“9堰槽类型”→“3梯形堰”→“1工作状态”项选择“开启”，并且在“2堰槛宽B”中输入实际实际渠道的堰槛宽，仪表就可以根据水位自动算出水位对应的流量。

④巴歇尔槽使用巴歇尔槽，可以在菜单“9堰槽类型”→“4巴歇尔槽”→“1工作状态”项选择“开启”，巴歇尔槽流量公式：Q=Cha n。

根据喉道宽“b”，从“附表二巴歇尔槽水位-流量公式”中查出修工系数c和指数n，输入到菜单“9堰槽类型”→“4巴歇尔槽”→“2修工系数c”和“3指数n”。
