This APP works with Tecom VB-800 Smart Wireless Vibration Temperature Sensor which is installed on rotating machine. User can read the real-time operation information (three-axis RMS vibration of velocity & acceleration, the FFT of velocity & acceleration, raw data, single point temperature), Health Index and Maintenance Schedule Suggestion of the machine through this APP. The information can also be uploaded to the remote management platform to perform functions such as storage, trend comparison, diagnostic analysis and report output. It provides predictive maintenance and be prepared for the worst.
Pipe Diameter Calculators
Read full descriptionHide full description
Size a pipe from the numbers you already have. Pipe Diameter Calculator finds the internal diameter of a circular pipe from your flow rate and target flow velocity, or checks the velocity in a pipe whose internal diameter you already know. Built for quick line sizing on site, at the desk or in class, it suits piping, mechanical and process engineers, plumbing and HVAC professionals, pipefitters and engineering students. TWO WAYS TO CALCULATE โข Find the internal diameter: enter the flow rate, fluid density and target velocity โข Check flow velocity: enter a known internal diameter and the flow rate VOLUME OR MASS FLOW โข Start from a volume flow rate or a mass (weight) flow rate โข Choose your inputs and the value to solve for on the Selection screen CLEAR RESULTS โข Cross-sectional area of the pipe โข Weight (mass) flow rate โข Flow velocity โข Internal pipe diameter METRIC AND IMPERIAL UNITS โข Pick a unit for each input and each result from its own menu โข Mix units freely, for example enter the diameter in centimeters and read the velocity in feet per second SIMPLE AND PRIVATE โข One clean screen, a Calculate button and a one-tap clear button โข Free to download โข No data collected HOW IT HELPS DAY TO DAY โข Pick a starting pipe size for a new line before you check it against your design standard โข Check whether the velocity in an existing pipe is reasonable for the duty โข Work through flow and velocity exercises for coursework and exams Results are a quick engineering estimate based on the values you enter. Always confirm final pipe sizes against the codes, standards and design criteria that apply to your project. Download Pipe Diameter Calculator and size your next line in seconds.

Verdict
The clearest difference is in-app purchases: Dr VB800 at none against Pipe Diameter Calculators's 1. Dr VB800 also leads on update cadence (every 5 weeks vs every 20 months) and iOS requirement (12.0 vs 15.6). On price, ads and device support there is nothing between them.
