Telemetry is the collection of measurements or other data at remote or inaccessible points and their automatic transmission to receiving equipment for monitoring.The word is derived from Greek the roots tele, "remote", and metron, "measure". Systems that need external instructions and data to operate require the counterpart of telemetry, telecommand.
Although the term commonly refers to wireless data transfer mechanisms (e.g., using radio, ultrasonic, or infrared systems), it also encompasses data transferred over other media such as a telephone or computer network, optical link or other wired communications like power line carriers. Many modern telemetry systems take advantage of the low cost and ubiquity of GSM networks by using SMS to receive and transmit telemetry data.
A telemeter is a device used to remotely measure any quantity. It consists of a sensor, a transmission path, and a display, recording, or control device. Telemeters are the physical devices used in telemetry. Electronic devices are widely used in telemetry and can be wireless or hard-wired, analog or digital. Other technologies are also possible, such as mechanical, hydraulic and optical.[3]

Answer:
Telemetry is an essential part of modern instrumentation systems. It refers to the process of transferring data from remote locations to a central control point. The use of telemetry in instrumentation systems is necessary for several reasons.
Explanation:
- First, telemetry enables real-time monitoring of remote systems. This means that if changes or problems arise, they can be identified and corrected immediately, avoiding downtime or damage.This is especially important in industries like aerospace, where remote systems are critical and downtime can have serious consequences.
- Second, telemetry allows data to be collected from remote systems over long periods of time. This data can be analyzed to identify trends and patterns, and can be used to optimize system performance and spot potential problems before they become serious.
- Finally, telemetry allows remote control of systems. This means operators can adjust system parameters or perform maintenance tasks without having to be physically present at the system location.This improves safety and efficiency and can reduce travel and maintenance costs.
In general, telemetry is an essential component of modern instrumentation systems, enabling real-time monitoring, data acquisition and analysis, and remote control of critical systems.
