China Flo-Instruments Co., Ltd Company Cases

Flo-Instruments' products have been applied successfully in many flow measurement and energy measurement projects of Building Management System (Usually referred to as BMS). For the flow/energy measurement of building automation, it is embodied in the following aspects:   1. HVAC (Heat Ventilation & Air Conditioning)   A comprehensive metering program is essential to effectively manage and conserve HVAC resources in buildings. While traditional methods using a building control system is to calculate energy building optimization, Flo-Instruments' wide range of energy flow meters offer superior accuray with traceable calibration for the entire measurement system in HVAC industries. With an integral display and multiple outputs, our wide range of energy flow meters provide, flow, temperature, energy consumption, etc.   2. Hot and Chilled water   Universities, Hospitals, Shopping Malls and all commercial buildings have central energy plants that provide chilled and hot water distribution throughout the buildings. The energy plants are often times managed by facility management companies that bill their customers for the amount hot water or chilled water being used. Our ultrasonic energy meters is used as a non-intrusive energy flow meter without interrupting the flow of heating and cooling water to the buildings. This saves a consider amount of installation and operation costs since there is no need for flow shut down or cutting the pipe to install.   Our ST501-PT100 and ST502-PT100 energy flow meters have been used in water and energy measurement for chiller optimization, hot water consumption monitoring, and primary & secondary heat exchanger flow monitoring. Flo-Instruments' ultrasonic flow meters have been used for energy balancing optimization and provides a one-stop shop for all of your energy meter and flow metering requirements in the Building Automation industry.

Ultrasonic flow meters offer a quick and easy solution to flow monitoring that be added at almost any point in a system.   Ultrasonic flow meters use a signal transmitted through the liquid from one sensor to another, the flow meter then measures the difference in the upstream and downstream transit time which is used to calculate the velocity of the water that is then converted into a flow rate.   That’s why ultrasonic flow meters are the primary building block in aquaculture processes – they not only deliver this important data, they also guarantee higher efficiency and safety.

WHAT IS AN HVAC SYSTEM   Air conditioning system, including temperature, humidity, air cleanliness and air circulation, is called HVAC (Full Name: Heating, Ventilation, Air conditioning and Cooling). This system provides heating and cooling to residential and commercial buildings. You can find HVAC systems anywhere from single-family homes to cruise ship where HVAC provides the means for environmental comfort. Becoming more and more popular in new construction, these systems use fresh air from outdoors to provide high indoor air quality.   APPLICATION OF ULTRASONIC FLOW METER Contemporary systems for heating, ventilation and air conditioning (HVAC) rely to a great extent on technology for flow and energy calculation. Owners of commercial and industrial facilities aim to deploy advanced flow metering solutions that allow them to accomplish optimum hydronic cooling and heating levels, even under very difficult conditions. In chilled/hot water systems, the reliability and efficiency of pumps may have a huge effect on running costs and performance.   To change the chilled/hot water flow, many construction systems now combine variable speed drives with pumps. Without losing resources or augmenting the wear on facilities, this method suits the water flow to the building’s needs.   In recent years, ultrasonic transit time flow measures have emerged as a common alternative for HVAC-related applications. Ultrasonic waves propagate upstream and downstream across the pipe wall and through the liquid circulating in the pipe with this technology. The meter measures the speed and flow rate by calculating the deviation in the travel time and understanding the pipe dimension.   Clamp-on flow meters for ultrasonic transit time can validate that water is correctly circulated through piping loops for HVAC units’ chilled and hot water sides, so that pumps can pass water via the system in a manner that guarantees higher efficiency and reduced costs of the asset life cycle.

Ultrasonic flow meter can monitor and measure the flow of water in real time. It's not only single water, but the water will also be divided into lots of catogories:   1. Regular water City water Well water Sea water River water Potable water District heating/cooling water Metropolitan water distribution Water in residential or commercial buildings Water in Irrigation and Agricultural Water in fish farming/aquaculture Cooling water in data center   2. Sewage & Wastewater Treatment Plants Sewage inlet flow Sewage outlet flow or any flow with particles less than 2% Raw sewage Reclaimed water Processed water   Whatever, Flo-Instru ultrasonic flow meters can measure the flow and flow velocity of relatively clean liquids in full pipes, with or without system shutdown and are designed to deliver highly accurate flow measurement in hydronic and domestic water applications etc. In this respection, Flo-Instruments already has relatively mature technology and services.

How the Meters Work   Unlike mechanical meters, ultrasonic meters use solid-state, ultrasonic measurement technology. Because there is no need to move parts, these devices improve accuracy and long-term reliability. Doppler meters typically provide 2% accuracy, but transit-time meters offer 1% to 2%of rate accuracy.   In the past, industrial development uses ultrasonic meters primarily to measure large volume applications such as raw water and water treatment. Compared with traditional measurement technologies, the meters have gradually gained acceptance because of several advantages:   Wide measuring range High accuracy High repeatability No moving parts to wear out or generate noise Minimal intrusion No need to shut pipeline for installation No pressure requirement No contact liquid Bidirectional design No additional cost for minimal maintenance   In Summary   Although traditional mechanical flow meters remain popular in industrial water treatment and wastewater environments, constant innovations are helping ultrasonic flow meters step into bigger market. Professionals worldwide are realizing the benefits of reduced installation and lifecycle costs gained by selecting ultrasonic metering technologies for industrial water applications.

Introduction   Modern industrial facilities have complex operational processes, which involve a wide range of flow measurement tasks. With growing awareness that water resources exist in limited quantities, there is an urgent need to save, reuse and recycle water, as well as develop methodologies to improve resource management. A key challenge for plant operators is meeting ever-increasing regulatory requirements while at the same time reducing operational costs.   Many industrial sites rely heavily on water for much of their operations. Used for everything from producing steam to cooling various systems to maintaining overall machinery, water serves as a precious commodity that manufacturing facilities can’t afford to be without.       Flow Measurement Challenges   Water and wastewater treatment systems require accurate measurement of flow to ensure reliable and cost-effective operation. Flow meters must be able to measure liquid across all phases, including large volumes of fluid carrying suspended solids, sludge by-products and other materials. Meters are also needed to measure the dosage of treatment chemicals.

Application Details:   Model: PH301 Pipe Material: Carbon Steel Pipe Size: 3824mm Thickness: 12mm Liquid: Water Location: Peru Application: Water Treatment Plant   A large water treatment plant is located in Peru. Because the pipe diameter is super large (pipe diameter is 3800mm, wall thickness is 12mm), after comprehensive analysis and demonstration of the measured liquid and various flowmeters, the customer finally chose the portable ultrasonic flowmeter.   High accuracy, wide pipe size range and portability enable customers to accurately measure the flow in the pipeline at any time and any place.
