Product Introduction
E8 series BMS water meter is a state-of-the-art transit time ultrasonic energy meter. Designed using the latest digital technology and low-voltage broadband pulse transmission.While principally designed for full-pipe clean liquid applications.The instrument is tolerant of liquids with small amounts of air bubbles or suspended solids found in most industrial environments. Comparing with other traditional flowmeter or ultrasonic flowmeter, it has distinctive features such as high precision, high reliability, high capability and low cost for BMS water measurement, other features: TVT technology designed. Less hardware components, low voltage broadband pulse transmission, low consumption power. Clear, user-friendly menu selections make flowmeter simple and convenient to use. Daily, monthly and yearly totalized flow. Parallel operation of positive, negative and net flow totalizes with scale factor (span) and 7 digit display, while the output of totalize pulse and frequency output are transmitted via relay and open collector.
E8 series ultrasonic energy meter that can realize the bidirectional independent BMS water measurement function of "cold" and "hot". It adopts advanced modular all-in-one design, independent menu operation, LCD backlight display, and it is suitable for the continuous measurement of cooling and heating energy of central air conditioning's chilled water and cooling water, meeting different measurement requirements. The unique digital signal processing technology enhances the anti-interference ability. Combined with the precision clamp on/insertion flow sensor and clamp on PT1000 temperature sensor, E8 features more stable measurement signal, more accurate measurement, simpler installation way, easier maintenance mode.

FAQ
Q: What are the advantages of BMS water meters?
A: BMS BTU meters offer advantages such as high accuracy, no moving parts, low maintenance requirements, and the ability to measure a wide range of flow rates. They are also suitable for various fluids and are non-intrusive, meaning they do not interfere with the flow.
Q: Do ultrasonic BTU meters require regular maintenance in BMS measurement?
A: E8 is low-maintenance device as it has no moving parts. However, periodic checks and calibrations may be recommended to ensure continued accuracy. Regular inspection for fouling or build-up on transducers during the BMS measurement may also be necessary.
Q: Is BMS meter E8 suitable for high-temperature applications?
A: E8 is designed to handle high-temperature fluids, making them suitable for applications such as district heating systems or industrial processes involving elevated temperatures.
Q: Which type of water meter is used in industry?
A: Most water management and industrial installations use ultrasonic flow meters to measure water consumption. These devices are also well suited for drinking water supply – and can come with programmed switches and alarms.
Q: What is the purpose of water meters?
A: Water meters measure the volume of water used by residential and commercial building units that are supplied with water by a public water supply system. They are also used to determine flow through a particular portion of the system.
