A published example, with clear ownership
KROHNE's Krombacher Brewery report describes compressed-air consumption profiling and a pressure-compensated vortex metering solution. This historical application belongs to KROHNE, not WESIVO; the original report is linked below.
The planning steps that follow are WESIVO editorial guidance for a new enquiry. They do not describe additional work at that brewery or promise energy savings.
Draw the boundary before comparing totals
Start with a simple network sketch: the supply header, storage, branches, cross-connections and the production areas to be assessed. Give every proposed point a tag and show flow direction. Identify which consumers sit downstream of each point.
Keep a main-header total separate from branch totals. Adding a main meter to its own downstream meters double-counts the same delivery. If comparing supply with consumption, agree the time interval and consider storage changes or unmetered paths before calling the difference a leak. The sketch is a review document, not a claim that a particular meter arrangement is suitable.
Make the operating record useful
For each observation period, retain the start and end timestamps, production state, meter status, displayed quantity and reference conditions. Record any known purge, cleaning or standby demand. An off-shift flow reading is a reason to investigate; it does not by itself identify a leak location or prove that all consumption is avoidable.
Preserve missing readings as missing. A communications outage must not silently become zero flow. When exporting totals, document resets, rollover and changes in configuration. Use the companion gas-flow guide before comparing values labelled m³/h, Nm³/h or standard volume.
Ask the supplier to review the actual duty
Submit the gas identity, expected condition, minimum/normal/maximum flow and the basis of those values. Add operating pressure and temperature, pipe dimensions, available installation space, upstream fittings and site photographs. Mark estimates explicitly.
Specify the receiving-system requirement separately: the quantity to be reported, its units, totaliser behaviour and the proposed output or protocol. Ask for the applicable installation and configuration documents for the complete order version. This article does not set universal straight-run lengths, accuracy or minimum detectable leakage.
Turn the plan into a reviewable enquiry
- A tagged network sketch with measurement boundaries and any unmetered connections.
- Flow ranges with actual or reference conditions stated in full.
- Pressure, temperature, gas condition and the source of each value.
- Installation photographs, receiving-system needs and requested documents.
- A comparison period, operational context and a list of unresolved questions.
Agree what evidence will be handed over: the approved configuration, reference-state settings, tag-to-signal mapping and a sample record with its units. Define the acceptance method with the project team rather than assuming that a consumption trend is a certified energy audit.
Product enquiry routes
The site lists Endress+Hauser t-mass F 500 as an international-brand gas-flow enquiry entry. It is a different product and measuring principle from the vortex instrument in the KROHNE case; no equivalence or transfer of case results is implied.
WESIVO 728 is a separate own-brand pressure-transmitter enquiry route for a pressure measurement point. It is not a flowmeter or an automatic leak-detection system. Confirm the required pressure reference, medium, range, connection and receiving interface. Neither listing establishes suitability, availability or a delivery commitment for this project.
公开案例及其归属
KROHNE 发布的 Krombacher 啤酒厂报告介绍了压缩空气用量画像和带压力补偿的涡街计量方案。这是 KROHNE 的历史应用，不是 WESIVO 项目，原始报告见文末。
下文为 WESIVO 编辑整理的新项目询价准备建议，不代表在该啤酒厂实施了额外工作，也不承诺节能结果。
先画清计量边界，再比较累计量
绘制简明管网图，标出供气总管、储气容积、支路、联通管和拟评估的生产区域。为每个拟测点编号，注明流向及其下游用气设备。
总管累计量与支路累计量分开列示。将总表与其下游分表相加，会重复统计同一份供气。若比较供气与用气，应先统一时间区间，考虑储气量变化及未计量通路，不能直接将差值命名为泄漏量。这张图用于技术复核，不表示任何具体布点方案已获确认。
让运行记录有解释依据
每个观察区间保留起止时间、生产状态、仪表状态、显示量及参考状态。另记已知的吹扫、清洗或待机用气。停产时出现流量值得调查，但单个读数不能直接定位漏点，也不能证明全部用量都可消除。
缺失读数应保持为缺失，通信中断不能悄悄变成零流量。导出累计量时，记录清零、溢出及配置变更。比较标为 m³/h、Nm³/h 或标准体积的数值前，先按配套技术文章核对计量口径。
请供应商结合实际工况复核
提供气体名称、预期状态、最小/正常/最大流量及其依据。附运行压力、温度、管道尺寸、可用安装空间、上游管件和现场照片。估计值应明确标注。
接收系统要求另行列项，包括需要报告的物理量、单位、累计量处理及拟用输出或协议。按完整订货版本索取安装和配置文件。本文不设定通用直管段长度、精度或可检测的最小泄漏量。
把方案整理成可复核的询价资料
- 带位号的管网图、计量边界及未计量的连接。
- 完整注明工况或参考状态的流量范围。
- 压力、温度、气体状态及各项数据来源。
- 安装照片、接收系统需求及所需文件。
- 比较区间、运行背景和仍待解决的问题。
预先约定交接内容：批准的配置、参考状态设置、位号与信号对应关系，以及带单位的样例记录。验收方法应由项目团队确认，不能默认一段用量趋势就是认证能源审计。
产品询价入口
本站列有国际品牌 Endress+Hauser t-mass F 500 气体流量产品入口。它与 KROHNE 案例中的涡街仪表属于不同产品和测量原理，本文不暗示等同替代或继承案例结果。
自有品牌 WESIVO 728 是独立压力测点的变送器询价入口，并非流量计或自动检漏系统。应确认压力基准、介质、量程、连接及接收接口。上述产品条目均不能直接作为本项目的适用性、库存或交期承诺。
