Ultrasonic Water Meter For Commercial & Industrial

·The meter is of multi-Channel design capable of marking double-section measurements with a highest possible measuring accuracy under various pipe flow conditions.

·The meter is of a though-bore design and has no mechanical moving parts. Because of no pressure loss, energy consumption of water pumps and hence operating costs of water supply enterprise is drastically reduced.

·The meter is battery powered with a micropower consumption design and a measuring cycle of one second. It can work uninterruptedly for a period of over 10 years with only one battery (Power consumption: <=0.5mW).

·The meter is high in reliability and is capable of keeping long-term working at any flowrate point without being affected by magnetic interference.

·It is highly sensitive to a minimal starting flowrate with a high accuracy (A flow velocity as low as 0.002m/s can be detected).

·It is provided with a multiple output-ting function. Through linking up with GSM for wireless data transmission, a monitoring system can be formed up for minitoring working state of meter and pipe network.

·The meter conform to South Africa standard<>.

Ex-Works calibration is made in conformity to South Africa standard <>.

·The meter is suitable for accurate measurement of flow of water delivered through urban water supply network, and the total water volume distribution to individual households (Main meter’s measured data). It can also find application on various industrial sites where power source are unavailable.

NEW! CryptoMate Nano Cryptographic USB Token

emmanuel — Fri, 01 Nov 2019 10:37:11 +0000

Overview

The CryptoMate Nano is the latest addition to the CryptoMate Token Series.

It contains the FIPS 140-2 Level 3-Certified ACOS5-64 v3.00 module, making it one of the most secured and portable cryptographic USB tokens in the market.

The CryptoMate Nano has 64 KB of EEPROM and complies with various international standards. Its casing is designed to be tamper-evident so that any unauthorized physical access will be easily visible. It also protects sensitive credentials and cryptographic keys since cryptographic operations such as RSA, SHA, AES and 3K3DES are performed on the ACOS5-64 module inside the token. With this, important and sensitive information is protected from being hacked or sniffed, achieving a high level of security for applications.
